This text provides an invaluable introduction to mechanicsm
confining attention to the motion of a particle. It begins with a
full discussion of the foundations of the subject within the
context of mathematical modelling before covering more advanced
topics including the theory of planetary orbits and the use of
rotating frames of reference. Truly introductory, the style adoped
is perfect for those unfamiliar with the subject and, as emphasis
is placed on understanding, readers who have already studied
maechanics will also find a new insight into a fundamental topic.
Low-Energy Nuclear Reactions and New Energy is a summary of
selected experimental and theoretical research performed over the
last 19 years that gives profound and unambiguous evidence for low
energy nuclear reaction (LENR), historically known as cold fusion.
In 1989, the subject was announced with great fanfare, to the
chagrin of many people in the science community. However, the
significant claim of its discoverers, Martin Fleischmann and
Stanley Pons, excess heat without harmful neutron emissions or
strong gamma radiation, involving electrochemical cells using heavy
water and palladium, has held strong.
In recent years, LENR, within the field of condensed matter nuclear
science, has begun to attract widespread attention and is regarded
as a potential alternative and renewable energy source to confront
climate change and energy scarcity. The aim of the research is to
collect experimental findings for LENR in order to present
reasonable explanations and a conclusive theoretical and practical
working model.
The goal of the field is directed toward the fabrication of LENR
devices with unique commercial potential demonstrating an
alternative energy source that does not produce greenhouse gases,
long-lived radiation or strong prompt radiation. The idea of LENR
has led to endless discussions about the kinetic impossibility of
intense nuclear reactions with high coulomb barrier potential.
However, recent theoretical work may soon shed light on this
mystery.
Understanding this process is one of the most challenging and
perhaps important issues in the scientific world. This book
includes previously unpublished studies, new and controversial
theories to approach LENR with access to new sources and
experimental results. The book offers insight into this
controversial subject and will help readers re-evaluate their
perspective on LENR as a possible alternative energy source.
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 textbook describes the physics of semiconductor nanostructures
with emphasis on their electronic transport properties. At its
heart are five fundamental transport phenomena: quantized
conductance, tunnelling transport, the Aharonov-Bohm effect, the
quantum Hall effect, and the Coulomb blockade effect.
The book starts out with the basics of solid state and
semiconductor physics, such as crystal structure, band structure,
and effective mass approximation, including spin-orbit interaction
effects important for research in semiconductor spintronics. It
contains material aspects such as band engineering, doping, gating,
and a selection of nanostructure fabrication techniques. The book
discusses the Drude-Boltzmann-Sommerfeld transport theory as well
as conductance quantization and the Landauer-Buttiker theory. These
concepts are extended to mesoscopic interference phenomena and
decoherence, magnetotransport, and interaction effects in
quantum-confined systems, guiding the reader from fundamental
effects to specialized state-of-the-art experiments.
The book will provide a thorough introduction into the topic for
graduate and PhD students, and will be a useful reference for
lecturers and researchers working in the field.
The neutron is an elementary particle that has been extensively
studied, both theoretically and experimentally. This book reviews
and analyses the results of the mainly experimental research on the
neutron and rationalizes what is known so far about its intrinsic
properties. The book covers topics that have not previously been
dealt with in detail, including the gravitational properties of the
neutron, precise determination of its mass, beta-decay, and its
electromagnetic properties. This translation is an updated version
of the original Russian text and also covers the more recent
advances made during the past 7-8 years, including the application
of methods based on the storage of ultra-cold neutrons to the study
of beta-decay, new precise measurement of the mass of the neutron,
and confirmation of modern theories of the internal structure of
the neutron.
The behaviour of electrons in systems without periodicity is one of
the most fascinating areas in solid-state physics, and the last 25
years have seen an enormous increase in research in this field.
This has given rise to many new ideas for understanding electronic
states in disordered systems, especially the study of the
degenerate electron gas in which electron-electron interactions are
important. This book provides a much needed survey of these
advances. In the first part of the book, the authors discuss
impurity bands in three dimensions. Attention is focused on the
regime in which the electrons are spatially localized rather than
free, so that an interesting interplay of localization and
interaction arises. In the second part of the book, they look at
the outstanding features of the two-dimensional systems, explaining
how these make the localization problem special and interesting.
The authors have provided a clear outline of the theoretical
picture for the chosen materials and description heuristic. Each
chapter is self-contained, allowing readers to pursue their special
interests.
Science is at a cross-roads. For several decades, the Standard
Model of particle physics has managed to fit vast amounts of
particle scattering data remarkably well, but many questions
remain. During those decades, some sophisticated theoretical
hypotheses such as string theory, quantum gravity, and quantum
cosmology have been proposed and studied intensively, in an effort
to break the log-jam of the Standard Model. None of those
hypotheses have succeeded to date. Of greater concern is the
increasing tendency by some practitioners in those fields to
downplay the empirical principles of science.In response, this book
is a restatement of those principles, covering numerous aspects of
observation. A particular focus is on contextuality versus realism,
the two fundamentally contrasting ideologies that underpin modern
physics.
Muography is a term recently introduced to embrace different
techniques that profit from the penetration capability of the muon
component of cosmic rays to investigate the interior of large and
otherwise inaccessible structures. Primary cosmic rays — high
energy particles originating outside the solar system — interact
with the Earth atmosphere and generate muons, particles with the
same electric charge as the electron, while their mass is 200 times
heavier. At the Earth's surface, cosmic muons represent the most
abundant component of cosmic rays, and favourably, they can feature
energies sufficiently high to penetrate even thick and dense
materials, giving the opportunity of unveiling the internal
structure of large volumes.Muography was made possible by the
development of detectors in the field of particle physics, allowing
the exploitation of this natural source for imaging in a vast
variety of fields, characterizing this technique as truly
interdisciplinary, and leading to significant advances in several
disciplines. This book tries to cover all aspects of this
methodology, with the different chapters pointing to the general
physics principles, to the technological and image reconstruction
challenges and to the principal applications in several fields,
such as archaeology and geology but also civil and industrial
applications.The volume contributors had omitted unnecessary
technical details, while focusing on the main features and
methodologies. Hence, the book not only targets scientists working
in the field but also non-specialists, who might enjoy the reading
as a tutorial.
This book is written for students who ever wondered about the
mysterious and fascinating world of particle accelerators. What
exciting physics and technologies lie within? What clever and
ingenious ideas were applied in their seven decades of evolution?
What promises still lay ahead in the future?Accelerators have been
driving research and industrial advances for decades. This textbook
illustrates the physical principles behind these incredible
machines, often with intuitive pictures and simple mathematical
models. Pure formalisms are avoided as much as possible. It is
hoped that the readers would enjoy the fascinating physics behind
these state-of-the-art devices.The style is informal and aimed for
a graduate level without prerequisite of prior knowledge in
accelerators. To serve as a textbook, references are listed only on
the more established original literature and review articles
instead of the constantly changing research frontiers.
Some twenty years ago the author published a book entitled The
Physics of Particle Detectors. Much has evolved since that time,
not in the basic physics, but in the complexity, number and
versatility of the detectors commonly used in experiments,
beam-lines and accelerators. Those changes have been heavily
influenced by the concurrent dramatic changes in the
microelectronics industry. In parallel, the use of computer-aided
teaching has also greatly improved. The present volume explores the
physics needed to understand the full suite of front-end devices in
use today. In particular the physics explanation is made
concurrently with the specific device being discussed, thus making
the coupling more immediate. That study is made more interactive by
using newer educational tools now available such as dynamic Matlab
Apps.
This book provides a brief exposition of the principles of beam
physics and particle accelerators with an emphasis on numerical
examples employing readily available computer tools. However, it
avoids detailed derivations, instead inviting the reader to use
general high-end languages such as Mathcad and Matlab, as well as
specialized particle accelerator codes (e.g. MAD, WinAgile,
Elegant, and others) to explore the principles presented. This
approach allows readers to readily identify relevant design
parameters and their scaling. In addition, the computer input files
can serve as templates that can be easily adapted to other related
situations. The examples and computer exercises comprise basic
lenses and deflectors, fringe fields, lattice and beam functions,
synchrotron radiation, beam envelope matching, betatron resonances,
and transverse and longitudinal emittance and space charge. The
last chapter presents examples of two major types of particle
accelerators: radio frequency linear accelerators (RF linacs) and
storage rings. Lastly, the appendix gives readers a brief
description of the computer tools employed and concise instructions
for their installation and use in the most popular computer
platforms (Windows, Macintosh and Ubuntu Linux). Hyperlinks to
websites containing all relevant files are also included. An
essential component of the book is its website (actually part of
the author's website at the University of Maryland), which contains
the files that reproduce results given in the text as well as
additional material such as technical notes and movies.
A P Balachandran has a long and impressive record of research in
particle physics and quantum field theory, bringing concepts of
geometry, topology and operator algebras to the analysis of
physical problems, particularly in particle physics and condensed
matter physics. He has also had an influential role within the
physics community, not only in terms of a large number of students,
research associates and collaborators, but also serving on the
editorial boards of important publications, including the
International Journal of Modern Physics A.This book consists of
articles by students and associates of Balachandran. Most of the
articles are scientific in nature, with topics ranging from
noncommutative geometry, particle physics phenomenology, to
condensed matter physics. Various chapters focus on new
perspectives and directions resulting from Balachandran's
contributions to physics, as well as some reminiscences of
collaborating and working with Balachandran.
This book provides a concise introduction to both the special
theory of relativity and the general theory of relativity. The
format is chosen to provide the basis for a single semester course
which can take the students all the way from the foundations of
special relativity to the core results of general relativity: the
Einstein equation and the equations of motion for particles and
light in curved spacetime. To facilitate access to the topics of
special and general relativity for science and engineering students
without prior training in relativity or geometry, the relevant
geometric notions are also introduced and developed from the ground
up. Students in physics, mathematics or engineering with an
interest to learn Einstein's theories of relativity should be able
to use this book already in the second semester of their third
year. The book could also be used as the basis of a graduate level
introduction to relativity for students who did not learn
relativity as part of their undergraduate training.
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.
This book covers introductory subjects including fundamental
principles of nuclear reactions with neutrons, fundamentals of
nuclear fission chain reactions, basic concepts of criticality, and
static characteristics based on diffusion approximation in neutron
transport. The chapters address topics ranging from neutron
moderation from fission to thermal energy ranges and heterogeneity
effects in neutronics. Readers will find elementary and qualitative
descriptions and also mathematical expressions including
approximations, derivations and analytical solutions for an
understanding of the basic principles of nuclear reactor physics.
This book is part of a series entitled An Advanced Course in
Nuclear Engineering and provides an accessible introduction to the
core discipline of nuclear engineering: nuclear reactor physics. It
will therefore appeal to engineers in nuclear engineering as well
as to university students and others seeking to learn entry-level
reactor physics.
Skyrmions - A Theory of Nuclei surveys 60 years of research into
the brilliant and imaginative idea of Tony Skyrme that atomic
nuclei can be modelled as Skyrmions, topologically stable states in
an effective quantum field theory of pions. Skyrme theory emerges
as a low-energy approximation to the more fundamental theory of
quarks and gluons - quantum chromodynamics (QCD). Skyrmions give
spatial structure to the protons and neutrons inside nuclei, and
capture the interactions of these basic particles, allowing them to
partially merge. Skyrme theory also gives a topological explanation
for the conservation of baryon number, a fundamental principle of
physics.The book summarises the particle and field theory
background, then presents Skyrme field theory together with the
mathematics needed to understand it. Many beautiful and
surprisingly symmetric Skyrmions are described and illustrated in
colour. Quantized Skyrmion motion models the momentum, energy and
spin of nuclei, and also their isospin, the quantum number
distinguishing protons and neutrons. Skyrmion vibrations also need
to be quantized, and the book reviews how the complicated energy
spectra of several nuclei, including Carbon-12 and Oxygen-16, are
accurately modelled by rotational/vibrational states of Skyrmions.
A later chapter explores variants of Skyrme theory, incorporating
mesons heavier than pions, and extending the basic theory to
include particles like kaons that contain strange quarks. The final
chapter introduces the Sakai-Sugimoto model, which relates
Skyrmions to gauge theory instantons in a higher-dimensional
framework inspired by string theory.

The first version of quantum theory, developed in the mid 1920's,
is what is called nonrelativistic quantum theory; it is based on a
form of relativity which, in a previous volume, was called Newton
relativity. But quickly after this first development, it was
realized that, in order to account for high energy phenomena such
as particle creation, it was necessary to develop a quantum theory
based on Einstein relativity. This in turn led to the development
of relativistic quantum field theory, which is an intrinsically
many-body theory. But this is not the only possibility for a
relativistic quantum theory. In this book we take the point of view
of a particle theory, based on the irreducible representations of
the Poincare group, the group that expresses the symmetry of
Einstein relativity. There are several ways of formulating such a
theory; we develop what is called relativistic point form quantum
mechanics, which, unlike quantum field theory, deals with a fixed
number of particles in a relativistically invariant way. A central
issue in any relativistic quantum theory is how to introduce
interactions without spoiling relativistic invariance. We show that
interactions can be incorporated in a mass operator, in such a way
that relativistic invariance is maintained. Surprisingly for a
relativistic theory, such a construction allows for instantaneous
interactions; in addition, dynamical particle exchange and particle
production can be included in a multichannel formulation of the
mass operator. For systems of more than two particles, however,
straightforward application of such a construction leads to the
undesirable property that clusters of widely separated particles
continue to interact with one another, even if the interactions
between the individual particles are of short range. A significant
part of this volume deals with the solution of this problem. Since
relativistic quantum mechanics is not as well-known as relativistic
quantum field theory, a chapter is devoted to applications of point
form quantum mechanics to nuclear physics; in particular we show
how constituent quark models can be used to derive electromagnetic
and other properties of hadrons.
Our understanding of subatomic particles developed over many years,
although a clear picture of the different particles, their
interactions and their inter-relationships only emerged in the
latter part of the twentieth century. The first ""subatomic
particles"" to be investigated were those which exhibit readily
observable macroscopic behavior, specifically these are the photon,
which we observe as light and the electron, which is manifested as
electricity. The true nature of these particles, however, only
became clear within the last century or so. The development of the
Standard Model provided clarification of the way in which various
particles, specifically the hadrons, relate to one another and the
way in which their properties are determined by their structure.
The final piece, perhaps, of the final model, that is the means by
which some particles acquire mass, has just recently been clarified
with the observation of the Higgs boson. Since the 1970s it has
been known that the measured solar neutrino flux was inconsistent
with the flux predicted by solar models. The existence of neutrinos
with mass would allow for neutrino flavor oscillations and would
provide an explanation for this discrepancy. Only in the past few
years, has there been clear experimental evidence that neutrinos
have mass. The description of particle structure on the basis of
the Standard Model, along with recent discoveries concerning
neutrino properties, provides us with a comprehensive picture of
the properties of subatomic particles. Part I of the present book
provides an overview of the Standard Model of particle physics
including an overview of the discovery and properties of the Higgs
boson. Part II of the book summarizes the important investigations
into the physics of neutrinos and provides an overview of the
interpretation of these studies.
This manual provides solutions to the problems given in the second
edition of the textbook entitled An Introduction to the Physics of
Particle Accelerators. Simple-to-solve problems play a useful role
as a first check of the student's level of knowledge whereas
difficult problems will test the student's capacity of finding the
bearing of the problems in an interdisciplinary environment. The
solutions to several problems will require strong engagement of the
student, not only in accelerator physics but also in more general
physical subjects, such as the profound approach to classical
mechanics (discussed in Chapter 3) and the subtleties of spin
dynamics (Chapter 13).
