Volume 54 of the Advances Series contains ten contributions,
covering a diversity of subject areas in atomic, molecular and
optical physics. The article by Regal and Jin reviews the
properties of a Fermi degenerate gas of cold potassium atoms in the
crossover regime between the Bose-Einstein condensation of
molecules and the condensation of fermionic atom pairs. The
transition between the two regions can be probed by varying an
external magnetic field. Sherson, Julsgaard and Polzik explore the
manner in which light and atoms can be entangled, with applications
to quantum information processing and communication. They report on
the result of recent experiments involving the entanglement of
distant objects and quantum memory of light. Recent developments in
cold Rydberg atom physics are reviewed in the article by Choi,
Kaufmann, Cubel-Liebisch, Reinhard, and Raithel. Fascinating
experiments are described in which cold, highly excited atoms
(???Rydberg??? atoms) and cold plasmas are generated. Evidence for
a collective excitation of Rydberg matter is also presented.
Griffiin and Pindzola offer an account of non-perturbative quantal
methods for electron-atom scattering processes. Included in the
discussion are the R-matrix with pseudo-states method and the
time-dependent close-coupling method. An extensive review of the
R-matrix theory of atomic, molecular, and optical processes is
given by Burke, Noble, and Burke. They present a systematic
development of the R-matrix method and its applications to various
processes such as electron-atom scattering, atomic photoionization,
electron-molecule scattering, positron-atom scattering, and
atomic/molecular multiphoton processes. Electron impactexcitation
of rare-gas atoms from both their ground and metastable states is
discussed in the article by Boffard, Jung, Anderson, and Lin.
Excitation cross sections measured by the optical method are
reviewed with emphasis on the physical interpretation in terms of
electronic structure of the target atoms. Ozier and Moazzen-Ahmadi
explore internal rotation of symmetric top molecules. Developments
of new experimental methods based on high-resolution torsional,
vibrational, and molecular beam spectroscopy allow accurate
determination of internal barriers for these symmetric molecules.
The subject of attosecond and angstrom science is reviewed by
Niikura and Corkum. The underlying physical mechanisms allowing one
to generate attosecond radiation pulses are described and the
technology needed for the preparation of such pulses is discussed.
LeGou??t, Bretenaker, and Lorger?? describe how rare earth ions
embedded in crystals can be used for processing optically carried
broadband radio-frequency signals. Methods for reaching tens of
gigahertz instantaneous bandwidth with submegahertz resolution
using such devices are analyzed in detail and demonstrated
experimentally. Finally, in the article by Illing, Gauthier, and
Roy, it is shown that small perturbations applied to optical
systems can be used to suppress or control optical chaos,
spatio-temporal dynamics, and patterns. Applications of these
techniques to communications, laser stabilization, and improving
the sensitivity of low-light optical switches are explored.
This book gathers selected papers from the first International Conference on Optoelectronics and Measurement (ICOM 2018), held in Hangzhou, China on Oct 18-20, 2018. The proceedings focus on the latest developments in the fields of optics, photonics, optoelectronics, sensors, and related measurement technologies. Addressing hot topics in fibre optics, photo detectors and sensors, it also features illustrations of advanced device technologies, explains measurement principles, and shares cutting-edge scientific and technological findings. Accordingly, readers will gain essential insights into the forefront of these fields, and will find not only important technical data, but also new ideas to inspire their own future research.
This book brings together two broad themes that have generated a great deal of interest and excitement in the scientific and technical community in the last 100 years or so: quantum tunnelling and nonlinear dynamical systems. It applies these themes to nanostructured solid state heterostructures operating at room temperature to gain insight into novel photonic devices, systems and applications.
This PhD thesis is dedicated to a subfield of elementary particle physics called "Flavour Physics". The Standard Model of Particle Physics (SM) has been confirmed by thousands of experimental measurements with a high precision. But the SM leaves important questions open, like what is the nature of dark matter or what is the origin of the matter-antimatter asymmetry in the Universe. By comparing high precision Standard Model calculations with extremely precise measurements, one can find the first glimpses of the physics beyond the SM - currently we see the first hints of a potential breakdown of the SM in flavour observables. This can then be compared with purely theoretical considerations about new physics models, known as model building. Both precision calculations and model building are extremely specialised fields and this outstanding thesis contributes significantly to both topics within the field of Flavour Physics and sheds new light on the observed anomalies.
New York Times bestseller Journey into the universe through the most spectacular sights in astronomy in stereoscopic 3D Welcome to the Universe in 3D takes you on a grand tour of the observable universe, guiding you through the most spectacular sights in the cosmos-in breathtaking 3D. Presenting a rich array of stereoscopic color images, which can be viewed in 3D using a special stereo viewer that folds easily out of the cover of the book, this book reveals your cosmic environment as you have never seen it before. Astronomy is the story of how humankind's perception of the two-dimensional dome of the sky evolved into a far deeper comprehension of an expanding three-dimensional cosmos. This book invites you to take part in this story by exploring the universe in depth, as revealed by cutting-edge astronomical research and observations. You will journey from the Moon through the solar system, out to exoplanets, distant nebulas, and galaxy clusters, until you finally reach the cosmic microwave background radiation (or CMB), the most distant light we can observe. The distances to these celestial wonders range from 1.3 light-seconds to 13.8 billion light-years. Along the way, the authors explain the fascinating features of what you are seeing, including how the 3D images were made using the same technique that early astronomers devised to measure distances to objects in space. The dramatic 3D images in this one-of-a-kind book will astonish you, extending your vision out to the farthest reaches of the universe. You will never look up into the night sky the same way again.
The first of its kind to explore the Nobel Prize experience "Dad, some guy is calling from Sweden." It was 2:30am on October 13th, 1998, the youngest son in the Laughlin house had answered the phone. His dad had just become a recipient of the Nobel Prize in physics. Frantic and funny events of the next two months are chronicled as the Laughlin's academic household morphs into a madcap staging area for the family and thirty guests who will be in attendance during Nobel week. From tickets to Stockholm to clothing measurements, Nobel lecture preparations, attach assistance and a quick trip to the White House for a formal reception with President and Mrs. Clinton, readers will laugh out loud while gasping in awe. The glorious Nobel ceremony and elaborate banquet is held each winter with a viewing audience of tens of millions. An intimate dinner with King Gustaf in his royal palace follows the Nobel evening in which Anita Laughlin finds herself the King's dinner partner for what becomes an evening of hilarious surprises, and yes, reindeer. This book is laced with cartoons drawn by Bob Laughlin that evoke collective feelings of surprise and bewilderment as he and his wife ascend the steep learning curve of Swedish protocol together.
Bacon and Osetsky present an atomistic model of
dislocation-particle interactions in metal systems, including
irradiated materials. This work is important in simulating actual
behavior, removing earlier reliance on assumed mechanisms for
dislocation motion. New mechanisms for dislocation generation under
shock loading are presented by Meyers et al. These models provide a
basis for understanding the constitutive behavior of shocked
material. Saada and Dirras provide a new perspective on the
Hall-Petch relation, with particular emphasis on nanocrystals. Of
particular significance, deviations from the traditional stress
proportional to the square-root of grain size relation are
explained. Robertson et al consider a number of effects of hydrogen
on plastic flow and provide a model that provides an explanation of
the broad range of properties. .
This book contains selected papers from the First International
Conference on the Ontology of Spacetime. Its fourteen chapters
address two main questions: first, what is the current status of
the substantivalism/relationalism debate, and second, what about
the prospects of presentism and becoming within present-day physics
and its philosophy? The overall tenor of the four chapters of the
book's first part is that the prospects of spacetime
substantivalism are bleak, although different possible positions
remain with respect to the ontological status of spacetime. Part II
and Part III of the book are devoted to presentism, eternalism, and
becoming, from two different perspectives. In the six chapters of
Part II it is argued, in different ways, that relativity theory
does not have essential consequences for these issues. It certainly
is true that the structure of time is different, according to
relativity theory, from the one in classical theory. But that does
not mean that a decision is forced between presentism and
eternalism, or that becoming has proved to be an impossible
concept. It may even be asked whether presentism and eternalism
really offer different ontological perspectives at all. The writers
of the last four chapters, in Part III, disagree. They argue that
relativity theory is incompatible with becoming and presentism.
Several of them come up with proposals to go beyond relativity, in
order to restore the prospects of presentism.
This book is devoted to an important branch of the dynamical systems theory: the study of the fine (fractal) structure of Poincare recurrences -instants of time when the system almost repeats its initial state. The authors were able to write an entirely self-contained text including many insights and examples, as well as providing complete details of proofs. The only prerequisites are a basic knowledge of analysis and topology. Thus this book can serve as a graduate text or self-study guide for courses in applied mathematics or nonlinear dynamics (in the natural sciences). Moreover, the book can be used by specialists in applied nonlinear dynamics following the way in the book. The authors applied the mathematical theory developed in the book to two important problems: distribution of Poincare recurrences for nonpurely chaotic Hamiltonian systems and indication of synchronization regimes in coupled chaotic individual systems.
This book describes the advanced stability theories for magnetically confined fusion plasmas, especially in tokamaks. As the fusion plasma sciences advance, the gap between the textbooks and cutting-edge researches gradually develops.
This book reports on the extraordinary observation of TeV gamma rays from the Crab Pulsar, the most energetic light ever detected from this type of object. It presents detailed information on the painstaking analysis of the unprecedentedly large dataset from the MAGIC telescopes, and comprehensively discusses the implications of pulsed TeV gamma rays for state-of-the-art pulsar emission models. Using these results, the book subsequently explores new testing methodologies for Lorentz Invariance Violation, in terms of a wavelength-dependent speed of light. The book also covers an updated search for Very-High-Energy (VHE), >100 GeV, emissions from millisecond pulsars using the Large Area Telescope on board the Fermi satellite, as well as a study on the promising Pulsar Wind Nebula candidate PSR J0631. The observation of VHE gamma rays is essential to studying the non-thermal sources of radiation in our Universe. Rotating neutron stars, also known as pulsars, are an extreme source class known to emit VHE gamma rays. However, to date only two pulsars have been detected with emissions above 100 GeV, and our understanding of their emission mechanism is still lacking.
The Textbook of Ion Channels is a set of three volumes providing a wide-ranging reference source on ion channels for students, instructors, and researchers. Ion channels are membrane proteins that control the electrical properties of neurons and cardiac cells, mediate the detection and response to sensory stimuli like light, sound, odor, and taste, and regulate the response to physical stimuli like temperature and pressure. In non-excitable tissues, ion channels are instrumental for the regulation of basic salt balance that is critical for homeostasis. Ion channels are located at the surface membrane of cells, giving them the unique ability to communicate with the environment, as well as the membrane of intracellular organelles, allowing them to regulate internal homeostasis. Ion channels are fundamentally important for human health and diseases, and are important targets for pharmaceuticals in mental illness, heart disease, anesthesia, pain and other clinical applications. The modern methods used in their study are powerful and diverse, ranging from single ion-channel measurement techniques to models of ion channel diseases in animals, and human clinical trials for ion channel drugs. All three volumes give the reader an introduction to fundamental concepts needed to understand the mechanism of ion channels, a guide to the technical aspects of ion channel research, offer a modern guide to the properties of major ion channel families, and include coverage of key examples of regulatory, physiological, and disease roles for ion channels.
The book Metaphysics in Contemporary Physics offers various perspectives on the relation and mutual influence between modern physical theories and analytic metaphysics. The authors of the contributions are philosophers of science, physicists and metaphysicians of international renown, and their work represents the cutting edge in modern metaphysics of physical sciences.
A mind-bending excursion to the limits of science and
mathematics
Modern physics has forever changed the way we view and understand
physical reality. With a wide spectrum of theories, from general
relativity to quantum mechanics, our conceptions of the very big
and the very small are no longer intuitively obvious. Many
philosophers, even scientists have expressed the opinion that the
counterintuitive conclusions posited in modern physics are best
understood using spiritual terminology. In the 11 lectures in this
volume, Harav Ginsburgh, one of our generation's foremost scholars,
innovators, and teachers of Kabbalah, reveals how modern physics
reflects foundational concepts in the Torah's inner dimension. A
wide range of topics from relativity (special and general), quantum
mechanics, and string theory are addressed. Elegantly and
gracefully, Harav Ginsburgh's exposition of the topics switches
back and forth between the scientific and Torah perspectives. With
his deep insight, Harav Ginsburgh gives even well-known physical
concepts a refreshing and new treatment. Apart from carefully
drawing parallels and correspondences between the Torah's inner
dimension and modern physics, in these lectures, Harav Ginsburgh
proposes new directions for scientific research into important
areas such as a unified field theory, CPT symmetry, the
relationship between acceleration and gravitation, and the
possibility of uncovering additional dimensions in physical
reality, demonstrating how the Torah's depth can be used to
fertilize science and further our understanding of nature.
