This book is on inertial confinement fusion, an alternative way to
produce electrical power from hydrogen fuel by using powerful
lasers or particle beams. Two huge laser facilities are presently
under construction to show that this method works. It involves the
compression of tiny amounts (micrograms) of fuel to thousand times
solid density and pressures otherwise existing only in the centre
of stars. Thanks to advances in laser technology, it is now
possible to produce such extreme states of matter in the
laboratory. Recent developments have boosted laser intensities
again with new possibilities for laser particle accelerators, laser
nuclear physics, and fast ignition of fusion targets. This is a
reference book for those working on beam plasma physics, be it in
the context of fundamental research or applications to fusion
energy or novel ultra-bright laser sources. The book combines quite
different areas of physics: beam target interaction, dense plasmas,
hydrodynamic implosion and instabilities, radiative energy transfer
as well as fusion reactions. Particular attention is given to
simple and useful modeling, including dimensional analysis and
similarity solutions. Both authors have worked in this field for
more than 20 years. They want to address in particular those
teaching this topic to students and all those interested in
understanding the technical basis.
This book focuses on the characteristics of optical radiation, or a
spectrum, emitted by various plasmas. In plasma, the same atomic
species can produce quite different spectra, or colors depending on
the nature of the plasma. This book gives a theoretical framework,
by which a particular spectrum can be interpreted correctly and
coherently. The uniqueness of the book lies in its comprehensive
treatment of the intensity distribution of spectral lines and the
population density distribution among the atomic levels, in plasma.
It is intended to provide beginners with a good perspective of the
field, laying out the physics in an extremely clear manner,
starting from an elementary level. A very useful feature of the
book is the asterisked sections and chapters which can be skipped
by readers, who only wish to gain a quick and basic introduction to
plasma spectroscopy. It will also be very useful to researchers
working actively in the field, acting as a guide for carrying out
experiments and interpreting experimental observations.
This book summarizes the enormous amount of material accumulated in
the field of nuclear density functional theory over the last few
decades. The goal of the theory is to provide a complete
quantum-mechanical description and explanation of nuclear phenomena
in terms of the local density distribution as a basic ingredient
rather than the many-particle wavefunction. This leads to a
considerable reduction in the mathematical complexity of nuclear
many-body problems and to a great conceptual simplicity and visual
clarity in its theoretical treatment. The authors develop the
mathematical framework on which the theory is based and consider
the associated approaches used to analyse experimental data in a
variety of nuclei and nuclear processes with widely differing
properties.
Recent advances witness the potential to employ nanomedicine and
game-changing methods to deliver drug molecules directly to
diseased sites. To optimize and then enhance the efficacy and
specificity, the control and guidance of drug carriers in
vasculature has become crucial. Current bottlenecks in the optimal
design of drug carrying particles are the lack of knowledge about
the transport of particles, adhesion on endothelium wall and
subsequent internalization into diseased cells. To study the
transport and adhesion of particle in vasculature, the authors have
made great efforts to numerically investigate the dynamic and
adhesive motions of particles in the blood flow. This book
discusses the recent achievements from the establishment of
fundamental physical problem to development of multiscale model,
and finally large scale simulations for understanding transport of
particle-based drug carriers in blood flow.
The transport of electric charge through most materials is well
described in terms of their electronic band structure. The present
book deals with two cases where the charge transport in a solid is
not described by the simple band structure picture of the solid.
These cases are related to the phenomena of the quantum Hall effect
and superconductivity. Part I of this book deals with the quantum
Hall effect, which is a consequence of the behavior of electrons in
solids when they are constrained to move in two dimensions. Part II
of the present volume describes the behavior of superconductors,
where electrons are bound together in Cooper pairs and travel
through a material without resistance.
Optical properties, particularly in the infrared range of
wavelengths, continue to be of enormous interest to both material
scientists and device engineers. The need for the development of
standards for data of optical properties in the infrared range of
wavelengths is very timely considering the on-going transition of
nano-technology from fundamental R&D to manufacturing.
Radiative properties play a critical role in the processing,
process control and manufacturing of semiconductor materials,
devices, circuits and systems. The design and implementation of
real-time process control methods in manufacturing requires the
knowledge of the radiative properties of materials. Sensors and
imagers operate on the basis of the radiative properties of
materials. This book reviews the optical properties of various
semiconductors in the infrared range of wavelengths. Theoretical
and experimental studies of the radiative properties of
semiconductors are presented. Previous studies, potential
applications and future developments are outlined. In Chapter 1, an
introduction to the radiative properties is presented. Examples of
instrumentation for measurements of the radiative properties is
described in Chapter 2. In Chapters 3-11, case studies of the
radiative properties of several semiconductors are elucidated. The
modeling and applications of these properties are explained in
Chapters 12 and 13, respectively. In Chapter 14, examples of the
global infrastructure for these measurements are illustrated.
Optics has been part of scientific enquiry from its beginning and
remains a key element of modern science. This book provides a
concise treatment of physical optics starting with a brief summary
of geometrical optics. Scalar diffraction theory is introduced to
describe wave propagation and diffraction effects and provides the
basis for Fourier methods for treating more complex diffraction
problems. The rest of the book treats the physics underlying some
important instruments for spectral analysis and optical metrology,
reflection and transmission at dielectric surfaces and the
polarization of light. This undergraduate-level text aims to aid
understanding of optical applications in physical, engineering and
life sciences or more advanced topics in modern optics.
The effect which now bears his name, was discovered in 1958 by
Rudolf Moessbauer at the Technical University of Munich. At first,
this appeared to be a phenomenon related to nuclear energy levels
that provided some information about excited state lifetimes and
quantum properties. However, it soon became apparent that
Moessbauer spectroscopy had applications in such diverse fields as
general relativity, solid state physics, chemistry, materials
science, biology, medical physics, archeology and art. It is the
extreme sensitivity of the effect to the atomic environment around
the probe atom as well as the ability to apply the technique to
some interesting and important elements, most notably iron, that is
responsible for the Moessbauer effect's extensive use. The present
volume reviews the historical development of the Moessbauer effect,
the experimental details, the basic physics of hyperfine
interactions and some of the numerous applications of Moessbauer
effect spectroscopy.
While neutron halos were discovered 30 years ago, this is the first
book written on the subject of this exotic form of nuclei that
typically contain many more neutrons than stable isotopes of those
elements. It provides an introductory description of the halo and
outlines the discovery and evidence for its existence. It also
discusses different theoretical models of the halo's structure as
well as models and techniques in reaction theory that have allowed
us to study the halo. This is written at a level accessible to
graduate students starting a PhD in nuclear physics. Halo nuclei
are an exotic form of atomic nuclei that contain typically many
more neutrons than stable isotopes of those elements. To give you a
famous example, an atom of the element lithium has three electrons
orbiting a nucleus with three protons and, usually, either 3 or 4
neutrons. The difference in the number of neutrons gives us two
different isotopes of lithium, Li6 and Li7. But if you keep adding
neutrons to the nucleus you will eventually reach Li11, with still
3 protons (that means it's lithium) but with 8 neutrons. This
nucleus is so neutron-rich that the last two are very weakly bound
to the rest of the nucleus (a Li9 core). What happens is a quantum
mechanical effect: the two outer neutrons float around beyond the
rest of the nuclear core at a distance that is beyond the range of
the force that is holding them to the core. This is utterly
counterintuitive. It means the nucleus looks like a core plus
extended diffuse cloud of neutron probability: the halo. The author
of the book, Jim Al-Khalili, is a theoretician who published some
of the key papers on the structure of the halo in the mid and late
90s and was the first to determine its true size. This monograph is
based on review articles he has written on the mathematical models
used to determine the halo structure and the reactions used to
model that structure.
Ours is an age of incredible breakthrough in science and
technology. Man has blazed a trail into outer space, built
'thinking machines' and made a giant progress, but yet he is not
fully aware of what exactly is inside the atom. The nucleus,
however remains somewhat a riddle. How are the nucleons packed
within a tiny nucleus? What is the nature of nuclear force? How can
the nucleus be smashed open to harness the tremendous energy, it
yields? The master theorists and experimenters have designed and
built huge machines called accelerators to probe into the nucleus
and solve nuclear mysteries. Particle science has gained prominence
and has emerged as exciting field of research. It is imperative,
therefore, that the young people interested in science read this
book. It is our firm belief that this book will also help many with
the crucial choice-their further studies and future occupation. We
feel this will make very interesting reading without unnecessarily
taxing the mind, but at the same time imparting the knowledge
required to complement a prescribed course on the topic.
Progress in Optics, Volume 62, an ongoing series, contains more
than 300 review articles by distinguished research workers that
have become permanent records for many important developments. In
this updated volume, users will find valuable updates on topics
such as optical testing, the modern aspects of intensity
interferometry with classical light, the generation of partially
coherent beams, optical models and symmetries, and more. This
book's contributions have become standard references in scientific
articles, providing the state-of-the-art to researchers and
practitioners who work in the field of optics.
The growing number of scientific and technological applications of
plasma physics in the field of Aerospace Engineering requires that
graduate students and professionals understand their principles.
This introductory book is the expanded version of class notes of
lectures I taught for several years to students of Aerospace
Engineering and Physics. It is intended as a reading guide,
addressed to students and non-specialists to tackle later with more
advanced texts. To make the subject more accessible the book does
not follow the usual organization of standard textbooks in this
field and is divided in two parts. The first introduces the basic
kinetic theory (molecular collisions, mean free path, etc.) of
neutral gases in equilibrium in connection to the undergraduate
physics courses. The basic properties of ionized gases and plasmas
(Debye length, plasma frequencies, etc.) are addressed in relation
to their equilibrium states and the collisional processes at the
microscopic level. The physical description of short and long-range
(Coulomb) collisions and the more relevant collisions (elementary
processes) between electrons' ions and neutral atoms or molecules
are discussed. The second part introduces the physical description
of plasmas as a statistical system of interacting particles
introducing advanced concepts of kinetic theory, (non-equilibrium
distribution functions, Boltzmann collision operator, etc). The
fluid transport equations for plasmas of electron ions and neutral
atoms and the hydrodynamic models of interest in space science and
plasma technology are derived. The plasma production in the
laboratory in the context of the physics of electric breakdown is
also discussed. Finally, among the myriad of aerospace applications
of plasma physics, the low pressure microwave electron multipactor
breakdown and plasma thrusters for space propulsion are presented
in two separate chapters.
Volume 3 of this three-part series presents more advanced topics
and applications of relativistic quantum field theory. The
application of quantum chromodynamics to high-energy particle
scattering is discussed with concrete examples for how to compute
QCD scattering cross sections. Experimental evidence for the
existence of quarks and gluons is then presented both within the
context of the naive quark model and beyond. Dr Strickland then
reviews our current understanding of the weak interaction, the
unified electroweak theory, and the Brout-Higgs-Englert mechanism
for the generation of gauge boson masses. The last two chapters
contain a self-contained introduction to finite temperature quantum
field theory with concrete examples focusing on the
high-temperature thermodynamics of scalar field theories, QED, and
QCD.
This book provides an itinerary to quantum mechanics taking into
account the basic mathematics to formulate it. Specifically, it
features the main experiments and postulates of quantum mechanics
pointing out their mathematical prominent aspects showing how
physical concepts and mathematical tools are deeply intertwined.
The material covers topics such as analytic mechanics in Newtonian,
Lagrangian, and Hamiltonian formulations, theory of light as
formulated in special relativity, and then why quantum mechanics is
necessary to explain experiments like the double-split, atomic
spectra, and photoelectric effect. The Schroedinger equation and
its solutions are developed in detail. It is pointed out that,
starting from the concept of the harmonic oscillator, it is
possible to develop advanced quantum mechanics. Furthermore, the
mathematics behind the Heisenberg uncertainty principle is
constructed towards advanced quantum mechanical principles.
Relativistic quantum mechanics is finally considered.The book is
devoted to undergraduate students from University courses of
Physics, Mathematics, Chemistry, and Engineering. It consists of 50
self-contained lectures, and any statement and theorem are
demonstrated in detail. It is the companion book of "A Mathematical
Journey to Relativity", by the same Authors, published by Springer
in 2020.
The present theme concerns the forces of nature, and what
investigations of these forces can tell us about the world we see
about us. The story of these forces is long and complex, and
contains many episodes that are not atypical of the bulk of
scientific research, which could have achieved greater acclaim 'if
only...'.The intention of this book is to introduce ideas of how
the visible world, and those parts of it that we cannot observe,
either because they are too small or too large for our scale of
perception, can be understood by consideration of only a few
fundamental forces. The subject in these pages will be the
authority of the commonly termed, laws of physics, which arise from
the forces of nature, and the corresponding constants of nature
(for example, the speed of light, c, the charge of the electron, e,
or the mass of the electron, me).
This book introduces the research process and principles of the
controlled super-coupling nuclear fusion experiment at the
Experimental Advanced Superconducting Tokamak (EAST) nuclear fusion
reactor in Hefei, China. It uses straightforward language to
explain how nuclear fusion can provide safe, environmentally
friendly, clean, and inexhaustible energy in future. EAST is the
world's first fully superconducting, non-circular cross-section
tokamak nuclear fusion experimental device, independently developed
by the Chinese Academy of Sciences. This book helps demonstrate
China's cutting-edge scientific and technological advances to the
rest of the world, helps spread the scientific spirit to people
around the globe, and promotes prosperity and development. The book
is intended for all non-experts who would like to learn more about
nuclear energy and related technologies.
This thesis explores two distinct applications of laser
spectroscopy: the study of nuclear ground state properties, and
element selective radioactive ion beam production. It also presents
the methods and results of an investigation into isotope shifts in
the mercury isotopic chain. These Resonance Ionization Laser Ion
Source (RILIS) developments are detailed, together with an RILIS
ionization scheme that allowed laser ionized ion beams of chromium,
germanium, radium and tellurium to be generated at the Isotope Mass
Separator On-Line (ISOLDE) facility. A combination of laser
spectroscopy with decay spectroscopy and mass spectrometry
unambiguously demonstrated a cessation of the extreme shape
staggering first observed in the 1970s and revealed the
characteristic kink at the crossing of the N=126 shell closure. A
series of RILIS developments were required to facilitate this
experiment, including mercury "ionization scheme" development and
the coupling of the RILIS with an arc discharge ion source. Laser
spectroscopy has since become a powerful tool for nuclear physics
and the Resonance Ionization Laser Ion Source (RILIS), of the
ISOLDE facility at CERN, is a prime example. Highlighting important
advances in this field, the thesis offers a unique and revealing
resource.
