There are reasons to believe the 21st century will be the best ever
for astrophysics: the James Webb Space Telescope will extend nearly
twenty times the present observational limit of visible light;
neutrino massiveness opens a new window for exploration on dark
energy and dark matter physics and is expected to provide insights
into the fate of the Universe; the Higgs boson may allow for an
understanding of the weakness of gravity; gravitational waves
produced at the birth of the Universe and by compact stellar
objects (supermassive black holes, black hole/neutron star mergers,
gamma-ray bursts, white dwarf inspirals) have unveiled a new area
of astronomy. Against this background, compact stars, the theme of
this volume, present unique astrophysical laboratories for probing
the fabric of space-time and the building blocks of matter and
their interactions at physical regimes not attainable in
terrestrial laboratories.
The arena of sport is filled with marvelous performances and feats
that, at times, seem almost beyond belief. As curious onlookers, we
often wonder whether or not athletes will reach certain peaks and
what determines their limits of athletic performance. Science, with
its emphasis on theoretical development and experimental results,
is uniquely equipped to answer these kinds of questions. Over the
past two decades, I have been asked innumerable questions related
to how science can provide these kinds of insights. Science in the
Arena is written as an outgrowth of those interactions with the
primary goal of communicating useful and understandable scientific
explanations of athletic performance.
Basic Optics: Principles and Concepts addresses in great detail the
basic principles of the science of optics, and their related
concepts. The book provides a lucid and coherent presentation of an
extensive range of concepts from the field of optics, which is of
central relevance to several broad areas of science, including
physics, chemistry, and biology. With its extensive range of
discourse, the book's content arms scientists and students with
knowledge of the essential concepts of classical and modern optics.
It can be used as a reference book and also as a supplementary text
by students at college and university levels and will, at the same
time, be of considerable use to researchers and teachers. The book
is composed of nine chapters and includes a great deal of material
not covered in many of the more well-known textbooks on the
subject. The science of optics has undergone major changes in the
last fifty years because of developments in the areas of the optics
of metamaterials, Fourier optics, statistical optics, quantum
optics, and nonlinear optics, all of which find their place in this
book, with a clear presentation of their basic principles. Even the
more traditional areas of ray optics and wave optics are elaborated
within the framework of electromagnetic theory, at a level more
fundamental than what one finds in many of the currently available
textbooks. Thus, the eikonal approximation leading to ray optics,
the Lagrangian and Hamiltonian formulations of ray optics, the
quantum theoretic interpretation of interference, the vector and
dyadic diffraction theories, the geometrical theory of diffraction,
and similar other topics of basic relevance are presented in clear
terms. The presentation is lucid and elegant, capturing the
essential magic and charm of physics. All this taken together makes
the book a unique text, of major contemporary relevance, in the
field of optics. Avijit Lahiri is a well-known researcher, teacher,
and author, with publications in several areas of physics, and with
a broad range of current interests, including physics and the
philosophy of science.

fractional calculus and their applications in diffusion and random
search processes. The book contains detailed calculations for
various examples of anomalous diffusion, random search and
stochastic resetting processes, which can be easily followed by the
reader, who will be able to reproduce the obtained results. The
book will be intended for advanced undergraduate and graduate
students and researchers in physics, mathematics and other natural
sciences due to the various examples which will be provided in the
book.
The unique compendium presents special principles and techniques of
spectroscopic measurements that are used in semiconductor
manufacturing.Since industrial applications of spectroscopy are
significantly different from those traditionally used in scientific
laboratories, the design concepts and characteristics of industrial
spectroscopic devices may vary significantly from conventional
systems. These peculiarities are thus succinctly summarized in this
volume for a wide audience of students, engineers, and scientific
workers.Exceptionally well-illustrated with practical solutions in
detail, this useful reference text will open new horizons in new
research areas.
A discourse on time, gravity, and the universe that takes the
reader through the subtleties of time, the origin of the universe,
and physical evolution in Einstein's theory and its extensions. Can
time and causality remain fundamental when the classical ideal of
spacetime becomes a concept of limited applicability in quantum
gravity? A thorough exposition on the canonical framework of
Einstein's theory and its extensions reveals the synergy between
gravitation and the cosmic clock of our expanding universe that
renders time concrete, physical, and comprehensible. In conjunction
with a paradigm shift from four-covariance to just spatial
diffeomorphism invariance, causal time-ordering of the quantum
state of the universe and its evolution in cosmic time become
meaningful. The quantum state of the universe is the embodiment of
our shared past, present, and future. The advocated framework
prompts natural extensions and improvements to Einstein's theory. A
salient feature is the addition of a Cotton-York term to the
physical Hamiltonian. Besides bringing improved ultraviolet
convergence, this radically changes the solution to the initial
data problem and the quantum origin of the universe. It lends
support to the quantum beginning of the universe as an exact
Chern-Simons Hartle-Hawking state that features
Euclidean-Lorentzian instanton tunneling. A signature of this state
is that it manifests, at the lowest order approximation,
scale-invariant two-point correlation function for
transverse-traceless quantum metric fluctuations. This initial
quantum state also implies, at the level of expectation values, a
low-entropy hot smooth Robertson-Walker beginning that is in accord
with Penrose's Weyl Curvature Hypothesis. Consequently, the
gravitational arrow of time of increasing spatial volume and the
thermodynamic second law arrow of time of increasing entropy concur
as our universe expands and ages.
The book focuses on the study of the temporal behavior of complex
many-particle systems. The phenomenon of time and its role in the
temporal evolution of complex systems is a remaining mystery. The
book presents the necessity of the interdisciplinary point of view
regarding on the phenomenon of time.The aim of the present study is
to summarize and formulate in a concise but clear form the trends
and approaches to the concept of time from a broad
interdisciplinary perspective exposing tersely the complementary
approaches and theories of time in the context of thermodynamics,
statistical physics, cosmology, theory of information, biology and
biophysics, including the problem of time and aging. Various
approaches to the problem show that time is an extraordinarily
interdisciplinary and multifaceted underlying notion which plays an
extremely important role in various natural complex processes.
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.

Few artworks have been the subject of more extensive modern
interpretation than Melencolia I by renowned artist, mathematician,
and scientist Albrecht Durer (1514). And yet, did each of these art
experts and historians miss a secret manifesto that Durer included
within the engraving? This is the first work to decrypt secrets
within Melencolia I based not on guesswork, but Durer's own
writings, other subliminal artists that inspired him (i.e.,
Leonardo da Vinci), the Jewish and Christian Bibles, and books that
inspired Durer (De Occulta Philosophia and the Hieorglyphica). To
read the covert message of Melencolia I is to understand that Durer
was a humanist in his interests in mathematics, science, poetry,
and antiquity. This book recognizes his unparalleled power with the
burin, his mathematical skill in perspective, his dedication to
precise language, and his acute observation of nature. Melencolia I
may also be one of the most controversial (and at the time most
criminal) pieces of art as it hid Durer's disdain for the hierarchy
of the Catholic Church, the Kaiser, and the Holy Roman Empire from
the general public for centuries. This book closely ties the
origins of philosophy (science) and the work of a Renaissance
master together, and will be of interest for anyone who loves
scientific history, art interpretation, and secret manifestos.
The study of dark matter, in both astrophysics and particle
physics, has emerged as one of the most active and exciting topics
of research in recent years. This book reviews the history behind
the discovery of missing mass (or unseen mass) in the Universe, and
ties this into the proposed extensions to the Standard Model of
Particle Physics (such as Supersymmetry), which were being proposed
within the same time frame. This book is written as an introduction
to these problems at the forefront of astrophysics and particle
physics, with the goal of conveying the physics of dark matter to
beginning undergraduate majors in scientific fields. The book goes
onto describe existing and upcoming experiments and techniques,
which will be used to detect dark matter either directly on
indirectly.

valuable reference considers the important engineering aspects of
design and implementation, energy generation, utilization and
energy conservation, intelligent control and monitoring data
analysis security, and asset integrity.
Tai Chi, a Chinese martial art developed based on the laws of
nature, emphasises how 'to conquer the unyielding with the
yielding.' The recent observation of star formation shows that
stars result from the interaction between gravity, turbulence and
magnetic fields. This interaction again follows the natural rules
that inspired Tai Chi. For example, if self-gravity is the force
that dominates, the molecular cloud will collapse isotropically,
which compresses magnetic field lines. The density of the yielding
field lines increases until magnetic pressure reaches the critical
value to support the cloud against the gravitational force in
directions perpendicular to the field lines (Lorentz force). Then
gravity gives way to Lorentz force, accumulating gas only along the
field lines till the gas density achieves the critical value to
again compress the field lines. The Tai Chi goes on in a self
similar way.
