Quartic anharmonic oscillator with potential V(x)= x(2) + g(2)x4
was the first non-exactly-solvable problem tackled by the
newly-written Schroedinger equation in 1926. Since that time
thousands of articles have been published on the subject, mostly
about the domain of small g(2) (weak coupling regime), although
physics corresponds to g(2) ~ 1, and they were mostly about
energies.This book is focused on studying eigenfunctions as a
primary object for any g(2). Perturbation theory in g(2) for the
logarithm of the wavefunction is matched to the true semiclassical
expansion in powers of : it leads to locally-highly-accurate,
uniform approximation valid for any g(2) [0, ) for eigenfunctions
and even more accurate results for eigenvalues. This method of
matching can be easily extended to the general anharmonic
oscillator as well as to the radial oscillators. Quartic, sextic
and cubic (for radial case) oscillators are considered in detail as
well as quartic double-well potential.
A world-recognized expert in the science of vehicle dynamics, Dr.
Thomas Gillespie has created an ideal reference book that has been
used by engineers for 30 years, ranging from an introduction to the
subject at the university level to a common sight on the desks of
engineers throughout the world. As with the original printing,
Fundamentals of Vehicle Dynamics, Revised Edition, strives to find
a middle ground by balancing the need to provide detailed
conceptual explanations of the engineering principles involved in
the dynamics of ground vehicles with equations and example problems
that clearly and concisely demonstrate how to apply such
principles. A study of this book will ensure that the reader comes
away with a solid foundation and is prepared to discuss the subject
in detail. Ideal as much for a first course in vehicle dynamics as
it is a professional reference, Fundamentals of Vehicle Dynamics,
Revised Edition, maintains the tradition of the original by being
easy to read and while receiving updates throughout in the form of
modernized graphics and improved readability.
Recent discoveries in astronomy and relativistic astrophysics as
well as experiments on particle and nuclear physics have blurred
the traditional boundaries of physics. It is believed that at the
birth of the Universe, a whirlwind of matter and antimatter, of
quarks and exotic leptons, briefly appeared and merged into a sea
of energy. The new phenomena and new states of matter in the
Universe revealed the deep connection between quarks and the
Cosmos. Motivated by these themes, this book discusses different
topics: gravitational waves, dark matter, dark energy, exotic
contents of compact stars, high-energy and gamma-ray astrophysics,
heavy ion collisions and the formation of the quark-gluon plasma in
the early Universe. The book presents some of the latest researches
on these fascinating themes and is useful for experts and students
in the field.
The clinical use of Artificial Intelligence (AI) in radiation
oncology is in its infancy. However, it is certain that AI is
capable of making radiation oncology more precise and personalized
with improved outcomes. Radiation oncology deploys an array of
state-of-the-art technologies for imaging, treatment, planning,
simulation, targeting, and quality assurance while managing the
massive amount of data involving therapists, dosimetrists,
physicists, nurses, technologists, and managers. AI consists of
many powerful tools which can process a huge amount of
inter-related data to improve accuracy, productivity, and
automation in complex operations such as radiation oncology.This
book offers an array of AI scientific concepts, and AI technology
tools with selected examples of current applications to serve as a
one-stop AI resource for the radiation oncology community. The
clinical adoption, beyond research, will require ethical
considerations and a framework for an overall assessment of AI as a
set of powerful tools.30 renowned experts contributed to sixteen
chapters organized into six sections: Define the Future, Strategy,
AI Tools, AI Applications, and Assessment and Outcomes. The future
is defined from a clinical and a technical perspective and the
strategy discusses lessons learned from radiology experience in AI
and the role of open access data to enhance the performance of AI
tools. The AI tools include radiomics, segmentation, knowledge
representation, and natural language processing. The AI
applications discuss knowledge-based treatment planning and
automation, AI-based treatment planning, prediction of radiotherapy
toxicity, radiomics in cancer prognostication and treatment
response, and the use of AI for mitigation of error propagation.
The sixth section elucidates two critical issues in the clinical
adoption: ethical issues and the evaluation of AI as a
transformative technology.
Discontinuous (first-order) phase transitions constitute the most
fundamental and widespread type of structural transitions existing
in Nature, forming a large majority of the transitions found in
elemental crystals, alloys, inorganic compounds, minerals and
complex fluids. Nevertheless, only a small part of them, namely,
weakly discontinuous transformations, were considered by
phenomenological theories, leaving aside the most interesting from
a theoretical point of view and the most important for application
cases. Discontinuous Phase Transitions in Condensed Matter
introduces a density-wave approach to phase transitions which
results in a unified, symmetry-based, model-free theory of the weak
crystallization of molecular mixtures to liquid-crystalline
mesophases, strongly discontinuous crystallization from molten
metals and alloys to conventional, fully segregated crystals, to
aperiodic, quasi-crystalline structures. Assembly of aperiodic
closed virus capsids with non-crystallographic symmetry also falls
into the domain of applicability of the density-wave approach.The
book also considers the applicability domains of the symmetry-based
approach in physics of low-dimensional systems. It includes
comparisons of stability of different surface superstructures and
metal monoatomic coverage structures on the surface of
single-crystalline substrates. The example of the twisted graphene
bilayer demonstrates how parametrization in the spirit of an
advanced phenomenological approach can establish
symmetry-controlled, and therefore model-free, links between
geometrical parameters of the twisted bilayer structure and
reconstruction of its Brillouin zone and energy bands.
Classical Mechanics teaches readers how to solve physics problems;
in other words, how to put math and physics together to obtain a
numerical or algebraic result and then interpret these results
physically. These skills are important and will be needed in more
advanced science and engineering courses. However, more important
than developing problem-solving skills and physical-interpretation
skills, the main purpose of this multi-volume series is to survey
the basic concepts of classical mechanics and to provide the reader
with a solid understanding of the foundational content knowledge of
classical mechanics. Classical Mechanics: Conservation Laws and
Rotational Motion covers the conservation of energy and the
conservation of momentum, which are crucial concepts in any physics
course. It also introduces the concepts of center-of-mass and
rotational motion.
Advanced fiber materials have been developed for various superior
applications because of their higher mechanical flexibility,
high-temperature resistance, and outstanding chemical stability.
This book presents an overview of the current development of
advanced fiber materials, fabrication methods, and applications.
Applications covered include pollution control, environment,
energy, information storage technology, optical and photonic,
photocatalysis, textile, drug delivery, tumor therapy, corrosion
protection applications, and a state of art of advanced fiber
materials.
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.
This book is written in a lucid and systematic way for advanced
postgraduates and researchers studying applied mathematics, plasma
physics, nonlinear differential equations, nonlinear optics, and
other engineering branches where nonlinear wave phenomena is
essential.In sequential order of the book's development, readers
will understand basic plasmas with elementary definitions of
magnetized and unmagnetized plasmas, plasma modeling, dusty plasma
and quantum plasma. Following which, the book describes linear and
nonlinear waves, solitons, shocks and other wave phenomena, while
solutions to common nonlinear wave equations are derived via
standard techniques. Readers are introduced to elementary
perturbation and non-perturbation methods. They will discover
several evolution equations in different plasma situations as well
as the properties of solitons in those environments. Pertaining to
those equations, readers will learn about their higher order
corrections, as well as their different forms and solutions in
non-planar geometry. The book offers further studies on different
types of collisions between solitons in plasma environment,
phenomena of soliton turbulence as a consequence of multi-soliton
interactions, properties of large amplitude solitary waves which
are discovered via non-perturbative Sagdeev's Pseudopotential
Approach, as well as the speed and shape of solitons. Finally, the
book reveals possible future developments of research in this rich
field.
The first part of this book overviews the physics of lasers and
describes some of the more common types of lasers and their
applications. Applications of lasers include CD/DVD players, laser
printers and fiber optic communication devices. Part II of this
book describes the phenomenon of Bose-Einstein condensation. The
experimental techniques used to create a Bose-Einstein condensate
provide an interesting and unconventional application of lasers;
that is, the cooling and confinement of a dilute gas at very low
temperature.
This book is the seventh volume of review chapters on advanced
problems of phase transitions and critical phenomena, the former
six volumes appeared in 2004, 2007, 2012, 2015, 2018, and 2020. The
aim of the book is to provide reviews in those aspects of
criticality and related subjects that are currently attracting much
attention due to essential new contributions.The book consists of
five chapters. They discuss criticality of complex systems, where
the new, emergent properties appear via collective behaviour of
simple elements as well as historical aspects of studies in the
field of critical phenomena. Since all complex systems involve
cooperative behaviour between many interconnected components, the
field of phase transitions and critical phenomena provides a very
natural conceptual and methodological framework for their study.As
the first six volumes, this book is based on the review lectures
that were given in Lviv (Ukraine) at the 'Ising lectures' - a
traditional annual workshop on complex systems, phase transitions
and critical phenomena which aims to bring together experts in
these fields with university students and those who are interested
in the subject.
With the rapid growth of new evidence from astronomy, space science
and biology that supports the theory of life as a cosmic rather
than terrestrial phenomenon, this book discusses a set of crucial
data and pictures showing that life is still arriving at our
planet. Although it could spark controversy among the most hardened
sceptics this book will have an important role in shaping future
science in this area.
Since the initial predictions for the existence of Weyl fermions in
condensed matter, many different experimental techniques have
confirmed the existence of Weyl semimetals. Among these techniques,
optical responses have shown a variety of effects associated with
the existence of Weyl fermions. In chiral crystals, we find a new
type of fermions protected by crystal symmetries — the chiral
multifold fermions — that can be understood as a higher-spin
generalization of Weyl fermions. This work provides a complete
description of all chiral multifold fermions, studying their
topological properties and the k·p models describing them. We
compute the optical conductivity of all chiral multifold fermions
and establish their optical selection rules. We find that the
activation frequencies are different for each type of multifold
fermion, thus constituting an experimental fingerprint for each
type of multifold fermion. Building on the theoretical results
obtained in the first part of our analysis, we study two chiral
multifold semimetals: RhSi and CoSi. We analyze the experimental
results with k·p and tight-binding models based on the crystal
symmetries of the material. We trace back the features observed in
the experimental optical conductivity to the existence of multifold
fermions near the Fermi level and estimate the chemical potential
and the scattering lifetime in both materials. Finally, we provide
an overview of second-order optical responses and study the
second-harmonic generation of RhSi. We find a sizeable
second-harmonic response in the low-energy regime associated with
optical transitions between topological bands. However, this regime
is extremely challenging to access with the current experimental
techniques. We conclude by providing an overview of the main
results, highlighting potential avenues to further research on
chiral multifold semimetals and the future of optical responses as
experimental probes to characterize topological phases.
