This volume contains the proceedings of the East Asia Joint
Symposium on Fields and Strings 2021, held at the Media Center of
Osaka City University on November 22-27, 2021. About 160 physicists
from all over East Asia attended physically or joined online this
symposium and more than 50 researchers presented their results in
the invited lectures, the short talks or the poster session.
Quantum field theory and string theory in the context of several
exciting developments were discussed, which include frontiers of
supersymmetric gauge theory, anomalies and higher form symmetries,
and several issues on quantum gravity and black holes.
This book covers different aspects of umbral calculus and of its
more recent developments. It discusses the technical details in
depth, including its relevant applications. The book has therefore
manyfold scopes to introduce a mathematical tool, not widespread
known as it should be; to present a complete account of the
relevant capabilities through the use of different examples of
applications; to provide a formal bridge between different fields
of research in pure and applied.
Physics and the Environment directly connects the physical world to
environmental issues that the world is facing today and will face
in the future. It shows how the first and second laws of
thermodynamics limit the efficiencies of fossil fuel energy
conversions to less than 100%, while also discussing how clever
technologies can enhance overall performance. It also extensively
discusses renewable forms of energy, their physical constraints and
how we must use science and engineering as tools to solve problems
instead of opinion and politics. Dr. Kyle Forinash takes you on a
journey of understanding our mature and well developed technologies
for using fossil fuel resources and how we are unlikely to see huge
gains in their efficiency as well as why their role in climate
change ought to be an argument for their replacement sooner rather
than later. He also discusses the newest technologies in employing
renewable resources and how it is important to understand their
physical constrains in order to make a smooth transition to them.
An entire chapter is dedicated to energy storage, a core question
in renewable energy as well as another chapter on the technical
issues of nuclear energy. The book ends with a discussion on how no
environmental solution, no matter how clever from a technical
aspect, will succeed if there are cheaper alternative, even if
those alternatives have undesirable features associated with them.
This book outlines the principles of thermoelectric generation and
refrigeration from the discovery of the Seebeck and Peltier effects
in the nineteenth century through the introduction of semiconductor
thermoelements in the mid-twentieth century to the more recent
development of nanostructured materials. It is shown that the
efficiency of a thermoelectric generator and the coefficient of
performance of a thermoelectric refrigerator can be related to a
quantity known as the figure of merit. The figure of merit depends
on the Seebeck coefficient and the ratio of the electrical to
thermal conductivity. It is shown that expressions for these
parameters can be derived from the band theory of solids. The
conditions for favourable electronic properties are discussed. The
methods for selecting materials with a low lattice thermal
conductivity are outlined and the ways in which the scattering of
phonons can be enhanced are described. The application of these
principles is demonstrated for specific materials including the
bismuth telluride alloys, bismuth antimony, alloys based on lead
telluride, silicon-germanium and materials described as
phonon-glass electron-crystals. It is shown that there can be
advantages in using the less familiar transverse thermoelectric
effects and the transverse thermomagnetic effects. Finally,
practical aspects of thermoelectric generation and refrigeration
are discussed. The book is aimed at readers who do not have a
specialised knowledge of solid state physics.
Quantum mechanics is one of the most fascinating, and at the
same time most controversial, branches of contemporary science.
Disputes have accompanied this science since its birth and have not
ceased to this day.
"Uncommon Paths in Quantum Physics" allows the reader to
contemplate deeply some ideas and methods that are seldom met in
the contemporary literature. Instead of widespread recipes of
mathematical physics, based on the solutions of
integro-differential equations, the book follows logical and partly
intuitional derivations of non-commutative algebra. Readers can
directly penetrate the abstract world of quantum mechanics.
First book in the market that treats this newly developed area of
theoretical physics; the book will thus provide a fascinating
overview of the prospective applications of this area, strongly
founded on the theories and methods that it describes.Provides a
solid foundation for the application of quantum theory to current
physical problems arising in the interpretation of molecular
spectra and important effects in quantum field theory.New insight
into the physics of anharmonic vibrations, more feasible
calculations with improved precision.
This book uses a hands-on approach to nonlinear dynamics using
commonly available software, including the free dynamical systems
software Xppaut, Matlab (or its free cousin, Octave) and the Maple
symbolic algebra system. Detailed instructions for various common
procedures, including bifurcation analysis using the version of
AUTO embedded in Xppaut, are provided. This book also provides a
survey that can be taught in a single academic term covering a
greater variety of dynamical systems (discrete versus continuous
time, finite versus infinite-dimensional, dissipative versus
conservative) than is normally seen in introductory texts.
Numerical computation and linear stability analysis are used as
unifying themes throughout the book. Despite the emphasis on
computer calculations, theory is not neglected, and fundamental
concepts from the field of nonlinear dynamics such as solution maps
and invariant manifolds are presented.
This book leapfrogs over the usual pedagogical progression, taking
readers to a real understanding of quantum, relativistic, nuclear
and particle physics. These areas are usually reserved for the end
of one's undergraduate career or even for graduate students in
physics programs, but do not need to be. The Scenic Route is really
created out of the joy of science; it is not designed to produce
problem-solving ability but rather is designed to reveal some
physics that is just plain nifty. Guided by an understanding that
much of modern physics is available to almost everyone with a
moderate mathematical vocabulary, we lead the student through a
short, trenchant tour of quantum physics, relativity, modern
particle physics and its history.Related Link(s)

Asian studies and Physics is a unique blend rarely found in a
Western scientific classroom. The field of Asian studies is rapidly
growing and the traditional study of Asian philosophy, art,
language and literature is branching out into scientific realms. At
the same time, there is a growing need to educate our young people
in science technology and mathematics (STEM). Reaching non-science
majors with the basic principles of physics presents a particularly
unique challenge. The topics presented in this work are designed to
appeal to a wide range of students and present scientific
principles through the technology and inventions of ancient China.
We explore these ideas in their historical Chinese context and
through the lens of our current scientific understanding. Our
exploration of ancient Chinese science is not limited to just a
theoretical understanding of physical principles. One distinction
of this book is the strong "hands on" component. Detailed
laboratory experiments are included which enable students to
analyze ancient technology using modern laboratory techniques. Each
experiment introduces the historical context and provides
associated Chinese vocabulary. On the surface, these experiments
involve recreating a Chinese technology. On a deeper level, we find
connections to the scientific method and techniques of experimental
analysis. Thus, an activity such as making paper, turns into a
lesson on statistics and graphical analysis. Topics included in
this volume cover one dimensional motion, energy conservation,
rotational equilibrium and elasticity. We also explore the nature
of science and include an introduction to the Chinese language.
Laboratory experiments cover papermaking, constructing a weighing
balance and stress-strain analysis of silk.
The applications of biocomposite materials are increasing in
aerospace, automobile, and household items due to their
biodegradable, renewable, non-corrosion, and high strength to
weight ratio properties. The processing and characterization of
biofiber-reinforced biocomposite materials are vital for their
strength and performance. This book discusses the properties,
chemical treatment, and compatibility of biofibers with materials.
Feynman path integrals are ubiquitous in quantum physics, even if a
large part of the scientific community still considers them as a
heuristic tool that lacks a sound mathematical definition. Our book
aims to refute this prejudice, providing an extensive and
self-contained description of the mathematical theory of Feynman
path integration, from the earlier attempts to the latest
developments, as well as its applications to quantum mechanics.This
second edition presents a detailed discussion of the general theory
of complex integration on infinite dimensional spaces, providing on
one hand a unified view of the various existing approaches to the
mathematical construction of Feynman path integrals and on the
other hand a connection with the classical theory of stochastic
processes. Moreover, new chapters containing recent applications to
several dynamical systems have been added.This book bridges between
the realms of stochastic analysis and the theory of Feynman path
integration. It is accessible to both mathematicians and
physicists.
Hulchul: The Common Ingredient of MotionMotionMotionMotion and Time
Author, Sohan Jain, proposes the following in the book: Instants of
Motion, Instants of Time and Time Outage: Just as time has instants
of time, motion has instants of motion, too. Instants of time and
motion can be divided into three classes: pure instants of time,
pure instants of motion, and composite instants of time and motion.
The sequences of the three types of instants are interspersed into
a single sequence of their occurrences. A body does not experience
time during pure instants of motion, a phenomenon we will call time
outage -the cause of time dilation. Time outage is not continuous;
it is intermittent. Internal and external motion of a body and
their inheritance: Each body has, generally, two kinds of motions:
internal motion and external motion. A body goes, wherever its
outer bodies go. An inner body inherits external motion of its
outer bodies. An outer body inherits internal motion of its inner
bodies. Photons and light do not inherit motion; may be, this is
why their motions are independent of their sources. Prime ticks,
the building blocks of time and any motion: Motion of a common body
is not continuous; it is intermittent. Any kind of motion is
perceived to be made of discrete, indivisible tiny movements,
called prime ticks (p-ticks). P-ticks are to motion what elementary
particles are to matter or what photons are to light. There is time
only because there is motion. Prime ticks are events and imply
motion. Events have concurrency, which implies time. Total
concurrency hulchul, a universal constant: Concurrency events of
external and internal p-ticks of a body are precisely the instants
of motion and time. The sum of the two is called the total
concurrency hulchul (c-hulchul). Total c-hulchul is the same for
all bodies. The proposed theory possibly explains: Why a particle
accelerator works. Why atoms have compartmentalized internal
structure. Why lighter bodies, such as elementary particles and
photons, have wavy straight motion rather than straight motion. The
theory predicts: The sharing of an electron by two atoms is not
continuous; it alternates between the two atoms.
