This book introduces readers to the characteristic features of
electromagnetic phenomena in superconductivity. It first
demonstrates not only that the diamagnetism in the
superconductivity complies with Maxwell's theory, which was
formulated before the discovery of superconductivity, but also that
the dominant E-B analogy in the electromagnetism loses perfection
without the superconductivity. The book then explores flux pinning,
which is responsible for the non-dissipative current in DC, leading
to irreversibility in AC. Drawing on Maxwell's work, it also proves
theoretically that if there is no energy dissipation in the
superconductivity caused by the break in time reversal symmetry, it
contradicts the thermodynamic principle of energy conservation -
something that had previously only been proved experimentally.
Lastly, the book addresses the longitudinal magnetic field effect,
and explains how this phenomenon leads to a new development of
Maxwell's theory. Featuring numerous appendices to help readers
understand the methods of derivation of equations, this book offers
students and young scientists an introduction to applied
superconductivity, especially in the context of power applications.
Presenting the characteristic features of electromagnetic phenomena
in superconductivity from basic to advanced topics for
applications, the book offers a valuable resource for graduate
students and researchers studying superconductivity as well as
engineers working in electric utility industry.
This thesis presents the first successful realization of a compact,
low-noise, and few-cycle light source in the mid-infrared
wavelength region. By developing the technology of pumping
femtosecond chromium-doped II-VI laser oscillators directly with
the emission of broad-stripe single-emitter laser diodes, coherent
light was generated with exceptionally low amplitude noise -
crucial for numerous applications including spectroscopy at high
sensitivities. Other key parameters of the oscillator's output,
such as pulse duration and output power, matched and even surpassed
previous state-of-the-art systems. As a demonstration of its unique
capabilities, the oscillator's powerful output was used to drive -
without further amplification - the nonlinear generation of
coherent mid-infrared light spanning multiple octaves. The
resulting table-top system uniquely combines high brilliance and
ultrabroad spectral bandwidth in the important mid-infrared
spectral range. The rapid development of this technology is
comprehensively and lucidly documented in this PhD thesis. Together
with a thorough review of literature and applications, and an
extensive analysis of the theoretical foundations behind ultrafast
laser oscillators, the thesis will serve as a valuable reference
for the construction of a new generation of mid-infrared light
sources.
This book describes the development, functioning, and results of a
successful binational program to promote significant scientific
advances in Earth-abundant photovoltaics (PV) and concentrated
solar power (CSP), advanced process/manufacturing technologies,
multiscale modeling and reliability testing, and analysis of
integrated solar energy systems. SERIIUS is a consortium between
India and the United States dedicated to developing new solar
technologies and assessing their potential impact in the two
countries. The consortium consists of nearly 50 institutions
including academia, national laboratories, and industry, with the
goal of developing significant new technologies in all areas of
solar deployment. In addition, the program focused on workforce
development through graduate students, post-doctoral students, and
an international exchange program. Particular emphasis was placed
on the following efforts: Creating disruptive technologies in PV
and CSP through high-impact fundamental and applied research and
development (R&D). Identifying and quantifying the critical
technical, economic, and policy issues for solar energy development
and deployment in India. Overcoming barriers to technology transfer
by teaming research institutions and industry in an effective
project structure. Building a new platform for binational
collaboration using a formalized R&D project structure, along
with effective management, coordination, and decision processes.
Creating a sustainable network and workforce development program
from which to build large collaborations and fostering a
collaborative culture and outreach programs. This includes using
existing and new methodologies for collaboration based on advanced
electronic and web-based communication to facilitate functional
international teams. The book summarizes the general lessons
learned from these experiences.
In this book, the authors cover the recent progress in the
synthesis, characterization and application of various
multi-layered carbides, carbonitrides and nitrides. Moreover, the
processing and development of MXene-based composites are
elaborated, focusing on their applications and performances as
transparent conductors in environmental remediation and energy
storage systems.
This book introduces recent progress in preparation and application
of core-shell and yolk-shell structures for attractive design of
catalyst materials. Core-shell nanostructures with active core
particles covered directly with an inert shell can perform as
highly active and selective catalysts with long lifetimes.
Yolk-shell nanostructures consisting of catalytically active core
particles encapsulated by hollow materials are an emerging class of
nanomaterials. The enclosed void space is expected to be useful for
encapsulation and compartmentation of guest molecules, and the
outer shell acts as a physical barrier to protect the guest
molecules from the surrounding environment. Furthermore, the
tunability and functionality in the core and the shell regions can
offer new catalytic properties, rendering them attractive platform
materials for the design of heterogeneous catalysts. This book
describes the recent development of such unique nanostructures to
design effective catalysts which can lead to new chemical
processes. It provides an excellent guide for design and
application of core-shell and yolk-shell structured catalysts for a
wide range of readers working on design of attractive catalysts,
photocatalysts, and electrocatalysts for energy, environmental, and
green chemical processes.
This book highlights the fundamental principles of optical fiber
technology required for understanding modern high-capacity
lightwave telecom networks. Such networks have become an
indispensable part of society with applications ranging from simple
web browsing to critical healthcare diagnosis and cloud computing.
Since users expect these services to always be available, careful
engineering is required in all technologies ranging from component
development to network operations. To achieve this understanding,
this book first presents a comprehensive treatment of various
optical fiber structures and diverse photonic components used in
optical fiber networks. Following this discussion are the
fundamental design principles of digital and analog optical fiber
transmission links. The concluding chapters present the
architectures and performance characteristics of optical networks.
This book provides a brief research source for optical fiber
sensors for energy production and storage systems, discussing
fundamental aspects as well as cutting-edge trends in sensing. This
volume provides industry professionals, researchers and students
with the most updated review on technologies and current trends,
thus helping them identify technology gaps, develop new materials
and novel designs that lead to commercially viable energy storage
systems.
This book presents a collection of "lessons" on various topics
commonly encountered in electronic circuit design, including some
basic circuits and some complex electronic circuits, which it uses
as vehicles to explain the basic circuits they are composed of. The
circuits considered include a linear amplifier, oscillators,
counters, a digital clock, power supplies, a heartbeat detector, a
sound equalizer, an audio power amplifier and a radio. The
theoretical analysis has been deliberately kept to a minimum, in
order to dedicate more time to a "learning by doing" approach,
which, after a brief review of the theory, readers are encouraged
to use directly with a simulator tool to examine the operation of
circuits in a "virtual laboratory." Though the book is not a theory
textbook, readers should be familiar with the basic principles of
electronic design, and with spice-like simulation tools. To help
with the latter aspect, one chapter is dedicated to the basic
functions and commands of the OrCad P-spice simulator used for the
experiments described in the book.
This book offers a concise primer on energy conversion efficiency
and the Shockley-Queisser limit in single p-n junction solar cells.
It covers all the important fundamental physics necessary to
understand the conversion efficiency, which is indispensable in
studying, investigating, analyzing, and designing solar cells in
practice. As such it is valuable as a supplementary text for
courses on photovoltaics, and bridges the gap between advanced
topics in solar cell device engineering and the fundamental physics
covered in undergraduate courses. The book first introduces the
principles and features of solar cells compared to those of
chemical batteries, and reviews photons, statistics and radiation
as the physics of the source energy. Based on these foundations, it
clarifies the conversion efficiency of a single p-n junction solar
cell and discusses the Shockley-Queisser limit. Furthermore, it
looks into various concepts of solar cells for breaking through the
efficiency limit given in the single junction solar cell and
presents feasible theoretical predictions. To round out readers'
knowledge of p-n junctions, the final chapter also reviews the
essential semiconductor physics. The foundation of solar cell
physics and engineering provided here is a valuable resource for
readers with no background in solar cells, such as upper
undergraduate and master students. At the same time, the deep
insights provided allow readers to step seamlessly into other
advanced books and their own research topics.

electronics, telecommunications, optical and information
technologies, focusing, in particular, on theoretical and practical
aspects of developing novel devices and materials, improving data
processing methods and technologies. The conference brings together
young researchers and early-career scientists participating in a
series of lectures and presentations, establishing contacts with
potential partners, sharing new project ideas and starting new
collaborations.
What are the physical mechanisms that underlie the efficient
generation and transfer of energy at the nanoscale? Nature seems to
know the answer to this question, having optimised the process of
photosynthesis in plants over millions of years of evolution. It is
conceivable that humans could mimic this process using synthetic
materials, and organic semiconductors have attracted a lot of
attention in this respect. Once an organic semiconductor absorbs
light, bound pairs of electrons with positively charged holes,
termed `excitons', are formed. Excitons behave as fundamental
energy carriers, hence understanding the physics behind their
efficient generation and transfer is critical to realising the
potential of organic semiconductors for light-harvesting and other
applications, such as LEDs and transistors. However, this problem
is extremely challenging since excitons can interact very strongly
with photons. Moreover, simultaneously with the exciton motion,
organic molecules can vibrate in hundreds of possible ways, having
a very strong effect on energy transfer. The description of these
complex phenomena is often beyond the reach of standard quantum
mechanical methods which rely on the assumption of weak
interactions between excitons, photons and vibrations. In this
thesis, Antonios Alvertis addresses this problem through the
development and application of a variety of different theoretical
methods to the description of these strong interactions, providing
pedagogical explanations of the underlying physics. A comprehensive
introduction to organic semiconductors is followed by a review of
the background theory that is employed to approach the relevant
research questions, and the theoretical results are presented in
close connection with experiment, yielding valuable insights for
experimentalists and theoreticians alike.
This book studies the fundamental aspects of many-body physics in
quantum systems open to an external world. Recent remarkable
developments in the observation and manipulation of quantum matter
at the single-quantum level point to a new research area of open
many-body systems, where interactions with an external observer and
the environment play a major role. The first part of the book
elucidates the influence of measurement backaction from an external
observer, revealing new types of quantum critical phenomena and
out-of-equilibrium dynamics beyond the conventional paradigm of
closed systems. In turn, the second part develops a powerful
theoretical approach to study the in- and out-of-equilibrium
physics of an open quantum system strongly correlated with an
external environment, where the entanglement between the system and
the environment plays an essential role. The results obtained here
offer essential theoretical results for understanding the many-body
physics of quantum systems open to an external world, and can be
applied to experimental systems in atomic, molecular and optical
physics, quantum information science and condensed matter physics.
This book focuses on the calculus of variations, including
fundamental theories and applications. This textbook is intended
for graduate and higher-level college and university students,
introducing them to the basic concepts and calculation methods used
in the calculus of variations. It covers the preliminaries,
variational problems with fixed boundaries, sufficient conditions
of extrema of functionals, problems with undetermined boundaries,
variational problems of conditional extrema, variational problems
in parametric forms, variational principles, direct methods for
variational problems, variational principles in mechanics and their
applications, and variational problems of functionals with vector,
tensor and Hamiltonian operators. Many of the contributions are
based on the authors' research, addressing topics such as the
extension of the connotation of the Hilbert adjoint operator,
definitions of the other three kinds of adjoint operators, the
extremum function theorem of the complete functional, unified Euler
equations in variational methods, variational theories of
functionals with vectors, modulus of vectors, arbitrary order
tensors, Hamiltonian operators and Hamiltonian operator strings,
reconciling the Euler equations and the natural boundary
conditions, and the application range of variational methods. The
book is also a valuable reference resource for teachers as well as
science and technology professionals.
This book discusses non-equilibrium quantum many-body dynamics,
recently explored in an analog quantum simulator of strongly
correlated ultracold atoms. The first part presents a
field-theoretical analysis of the experimental observability of the
Higgs amplitude mode that emerges as a relativistic collective
excitation near a quantum phase transition of superfluid Bose gases
in an optical lattice potential. The author presents the dynamical
susceptibilities to external driving of the microscopic parameters,
taking into account a leading-order perturbative correction from
quantum and thermal fluctuations and shows clear signatures of the
Higgs mode in these observables. This is the first result that
strongly supports the stability of the Higgs mode in
three-dimensional optical lattices even in the presence of a
spatially inhomogeneous confinement potential and paves the way for
desktop observations of the Higgs mode. In the second part, the
author applies the semi-classical truncated-Wigner approximation
(TWA) to far-from-equilibrium quantum dynamics. Specifically, he
considers the recent experiments on quantum-quench dynamics in a
Bose-Hubbard quantum simulator. A direct comparison shows
remarkable agreement between the numerical results from TWA and the
experimental data. This result clearly indicates the potential of
such a semi-classical approach in reliably simulating many-body
systems using classical computers. The book also includes several
chapters providing comprehensive reviews of the recent studies on
cold-atomic quantum simulation and various theoretical methods,
including the Schwinger-boson approach in strongly correlated
systems and the phase-space semi-classical method for
far-from-equilibrium quantum dynamics. These chapters are highly
recommended to students and young researchers who are interested in
semi-classical approaches in non-equilibrium quantum dynamics.
This book systematically reviews the history of lead-free
piezoelectric materials, including the latest research. It also
addresses a number of important issues, such as new types of
materials prepared in a multitude of sizes, structural and physical
properties, and potential applications for high-performance
devices. Further, it examines in detail the state of the art in
lead-free piezoelectric materials, focusing on the pathways to
modify different structures and achieve enhanced physical
properties and new functional behavior. Lastly, it discusses the
prospects for potential future developments in lead-free
piezoelectric materials across disciplines and for multifunctional
applications. Given its breadth of coverage, the book offers a
comprehensive resource for graduate students, academic researchers,
development scientists, materials producers, device designers and
applications engineers who are working on or are interested in
advanced lead-free piezoelectric materials.
The present book focuses on recent advances methods and
applications in photovoltaic (PV) systems. The book is divided into
two parts: the first part deals with some theoretical, simulation
and experiments on solar cells, including efficiency improvement,
new materials and behavior performances. While the second part of
the book devoted mainly on the application of advanced methods in
PV systems, including advanced control, FPGA implementation, output
power forecasting based artificial intelligence technique (AI),
high PV penetration, reconfigurable PV architectures and fault
detection and diagnosis based AI. The authors of the book trying to
show to readers more details about some theoretical methods and
applications in solar cells and PV systems (eg. advanced algorithms
for control, optimization, power forecasting, monitoring and fault
diagnosis methods). The applications are mainly carried out in
different laboratories and location around the world as projects
(Algeria, KSA, Turkey, Morocco, Italy and France). The book will be
addressed to scientists, academics, researchers and PhD students
working in this topic. The book will help readers to understand
some applications including control, forecasting, monitoring, fault
diagnosis of photovoltaic plants, as well as in solar cells such as
behavior performances and efficiency improvement. It could be also
be used as a reference and help industry sectors interested by
prototype development.
This significantly extended second edition addresses the important
physical phenomenon of Surface Plasmon Resonance (SPR) or Surface
Plasmon Polaritons (SPP) in thin metal films, a phenomenon which is
exploited in the design of a large variety of physico-chemical
optical sensors. In this treatment, crucial materials aspects for
design and optimization of SPR sensors are investigated and
described in detail. The text covers a selection of nanometer thin
metal films, ranging from free-electron to the platinum-type
conductors, along with their combination with a large variety of
dielectric substrate materials, and associated individual layer and
opto-geometric arrangements. Whereas the first edition treated
solely the metal-liquid interface, the SP-resonance conditions
considered here are expanded to cover the metal-gas interface in
the angular and wavelength interrogation modes, localized and
long-range SP's and the influence of native oxidic ad-layers in the
case of non-noble metals. Furthermore, a selection of metal grating
structures that allow SP excitation is presented, as are features
of radiative SP's. Finally, this treatise includes as-yet hardly
explored SPR features of selected metal-metal and metal-dielectric
superlattices. An in-depth multilayer Fresnel evaluation provides
the mathematical tool for this optical analysis, which otherwise
relies solely on experimentally determined electro-optical
materials parameters.
This monograph presents an intuitive theory of trial wave functions
for strongly interacting fermions in fractional quantum Hall
states. The correlation functions for the proposed fermion
interactions follow a novel algebraic approach that harnesses the
classical theory of invariants and semi-invariants of binary forms.
This approach can be viewed as a fitting and far-reaching
generalization of Laughlin's approach to trial wave functions.
Aesthetically viewed, it illustrates an attractive symbiosis
between the theory of invariants and the theory of correlations.
Early research into numerical diagonalization computations for
small numbers of electrons shows strong agreement with the
constructed trial wave functions.The monograph offers researchers
and students of condensed matter physics an accessible discussion
of this interesting area of research.
This textbook provides a sound foundation in physical optics by
covering key concepts in a rigorous but accessible manner.
Propagation of electromagnetic waves is examined from multiple
perspectives, with explanation of which viewpoints and methods are
best suited to different situations. After an introduction to the
theory of electromagnetism, reflection, refraction, and dispersion,
topics such as geometrical optics, interference, diffraction,
coherence, laser beams, polarization, crystallography, and
anisotropy are closely examined. Optical elements, including
lenses, mirrors, prisms, classical and Fabry-Perot interferometers,
resonant cavities, multilayer dielectric structures, interference
and spatial filters, diffraction gratings, polarizers, and
birefringent plates, are treated in depth. The coverage also
encompasses such seldom-covered topics as modeling of general
astigmatism via 4x4 matrices, FFT-based numerical methods, and
bianisotropy, with a relativistic treatment of optical activity and
the Faraday and Fresnel-Fizeau effects. Finally, the history of
optics is discussed.
Providing an introduction to the design of embedded microprocessor
systems, this edition covers everything from the initial concept
through to debugging the final result. It also includes material on
DMA, interrupts and an emphasis throughout on the real-time nature
of embedded systems. The book is not limited to describing any
specific processor family, but covers the operation of, and
interfaces to, several types of processors with an emphasis on cost
and design trade-offs Included throughout the book are numerous
examples, tips, and pitfalls to help readers find out how to
implement faster and better design processes and avoid
time-consuming and expensive mistakes. The author describes the
entire process of designing circuits, and the software that
controls them, assessing the system requirements, as well as
testing and debugging systems. In this third edition, there is an
expanded section on debug which includes avoiding common hardware,
software and interrupt problems. Other added features include an
expanded section on system integration and debug to address the
capabilities of more recent emulators and debuggers, a section
about combination microcontroller/PLD devices, and
This book presents research dedicated to solving scientific and
technological problems in many areas of electronics, photonics and
renewable energy. Energy and information are interconnected and are
essential elements for the development of human society.
Transmission, processing and storage of information requires energy
consumption, while the efficient use and access to new energy
sources requires new information (ideas and expertise) and the
design of novel systems such as photovoltaic devices, fuel cells
and batteries. Semiconductor physics creates the knowledge base for
the development of information (computers, cell phones, etc.) and
energy (photovoltaic) technologies. The exchange of ideas and
expertise between these two technologies is critical and expands
beyond semiconductors. Continued progress in information and
renewable energy technologies requires miniaturization of devices
and reduction of costs, energy and material consumption. The latest
generation of electronic devices is now approaching nanometer scale
dimensions, new materials are being introduced into electronics
manufacturing at an unprecedented rate, and alternative
technologies to mainstream CMOS are evolving. Nanotechnology is
widely accepted as a source of potential solutions in securing
future progress for information and energy technologies.
Semiconductor Nanotechnology features chapters that cover the
following areas: atomic scale materials design, bio- and molecular
electronics, high frequency electronics, fabrication of
nanodevices, magnetic materials and spintronics, materials and
processes for integrated and subwave optoelectronics, nanoCMOS, new
materials for FETs and other devices, nanoelectronics system
architecture, nano optics and lasers, non-silicon materials and
devices, chemical and biosensors, quantum effects in devices, nano
science and technology applications in the development of novel
solar energy devices, and fuel cells and batteries.
