Quantum physics may appear complicated, especially if one forgets the "big picture" and gets lost in the details. However, it can become clearer and less tangled if one applies a few fundamental concepts so that simplified approaches can emerge and estimated orders of magnitude become clear. Povh and Rosina's Scattering and Structures presents the properties of quantum systems (elementary particles, nucleons, atoms, molecules, quantum gases, quantum liquids, stars, and early universe) with the help of elementary concepts and analogies between these seemingly different systems. In this new edition, sections on quantum gases and an up to date overview of elementary particles have been added.
Market: Physicists, chemists, biochemists, and biologists. Here's the first book to gather the vast range of experimental data in electron spin resonance (ESR) into a single volume. Concise yet comprehensive, it offers an easy-to-use collection of up-to-date experimental data, methods, and theory. The Handbook includes key contributions from leading scientists and provides over 200 tables and figures. Although specific ESR subfields are covered in numerous books and journals, the Handbook of Electron Spin Resonance is the only comprehensive reference to present extensive tabulation of data and experimental results. The Handbook also provides introductions to theoretical backgrounds, methods, and instrumentation.
This book provides a comprehensive overview of the operating principles and technology of electron lenses in supercolliders. Electron lenses are a novel instrument for high energy particle accelerators, particularly for the energy-frontier superconducting hadron colliders, including the Tevatron, RHIC, LHC and future very large hadron colliders. After reviewing the issues surrounding beam dynamics in supercolliders, the book offers an introduction to the electron lens method and its application. Further chapters describe the technology behind the electron lenses which have recently been proposed, built and employed for compensation of beam-beam effects and for collimation of high-energy high-intensity beams, for compensation of space-charge effects and several other applications in accelerators. The book will be an invaluable resource for those involved in the design, construction and operation of the next generation of hadron colliders.
Novel coherent light sources such as x-ray free-electron lasers open exciting prospects for the interaction of light with nuclei. The thesis "Coherent Control of Nuclei and X-rays" covers this still-developing field and proposes, in a daring attempt to revolutionize nuclear physics, three innovative schemes for taming nuclei using coherent effects. The theoretical explorations, which address control of nuclear quantum states, a nuclear memory for single photons in future photonic circuits, and optimized concepts for a nuclear clock, make use of new approaches at the borderline between nuclear physics and quantum dynamics. The result is a well written work, impressive in its stimulating style and promising ideas.
The book presents asymptotic expansions of Feynman integrals in various limits of momenta and masses, and their applications to problems of physical interest. The problem of expansion is systematically solved by formulating universal prescriptions that express terms of the expansion using the original Feynman integral with its integrand expanded into a Taylor series in appropriate momenta and masses. Knowledge of the structure of the asymptotic expansion at the diagrammatic level is key in understanding how to perform expansions at the operator level. Most typical examples of these expansions are presented: the operator product expansion, the large-mass expansion, Heavy Quark Effective Theory, and Non-Relativistic QCD.
This thesis presents the first measurements of jets in relativistic heavy ion collisions as reported by the ATLAS Collaboration. These include the first direct observation of jet quenching through the observation of a centrality-dependent dijet asymmetry. Also, a series of jet suppression measurements are presented, which provide quantitative constraints on theoretical models of jet quenching. These results follow a detailed introduction to heavy ion physics with emphasis on the phenomenon of jet quenching and a comprehensive description of the ATLAS detector and its capabilities with regard to performing these measurements.
In "Single Molecule Studies of Proteins," expert researchers discuss the successful application of single-molecule techniques to a wide range of biological events, such as the imaging and mapping of cell surface receptors, the analysis of the unfolding and folding pathways of single proteins, the analysis interaction forces between biomolecules, the study of enzyme catalysis or the visualization of molecular motors in action. The chapters are aimed at established investigators and post-doctoral researchers in the life sciences wanting to pursue research in the various areas in which single-molecule approaches are important; this volume also remains accessible to advanced graduate students seeking similar research goals.
Lasers in Analytical Atomic Spectroscopy Edited by Joseph Sneddon • Terry L. Thiem • Yong-Ill Lee This book focuses primarily on the use of lasers in analytical atomic spectroscopy with optical detection, and also includes a chapter describing the use of lasers in inductively coupled plasma—mass spectroscopy (ICP—MS). The book begins with a brief introduction to atomic spectroscopy and lasers, providing the reader with basic theory and information on instrumentation in conventional atomic spectroscopy. Next, the properties, types, and principles of lasers are discussed using a non-mathematical approach. The main section of the book provides detailed descriptions of the four major areas of laser application in analytical atomic spectroscopy, each discussed by an expert in the field: laser excited atomic fluorescence spectrometry (LEAFS); laser ablation for sample introduction, particularly in inductively coupled plasma—atomic emission spectrometry (ICP—AES) and ICP—MS; laser induced breakdown (emission) spectrometry (LIBS); and laser-enhanced ionization (LEI) spectrometry. Lasers in Analytical Atomic Spectroscopy will be of interest to spectroscopists, analytical chemists, and graduate students in these areas.

Molecules are found in a large variety of astronomical environments, ranging from comets in the solar system to galaxies at high redshift. This book brings together astronomers, physicists and chemists to discuss the use of molecules as probes of astrophysical parameters, explore their role in the evolution of astronomical objects, and study the basic chemical processes that occur in space. The enormous progress in observational techniques is illustrated by studies of the physics and chemistry on scales comparable to the protosolar nebulae around high- and low-mass forming stars and planetary systems. Elegant new experimental techniques for the measurement of gas-phase reactions at low temperatures, the analysis of spectra, and the investigation of surface adsorbates on interplanetary dust particles and meteorites are presented; the importance of accurate quantum chemical calculations is emphasized. Present knowledge of the composition of dust grains and polycyclic aromatic hydrocarbons is summarized. Other topics include models and observations of jets and outflows, photon- and X-ray-dominated regions, masers in and outside our galaxy, the comet D/Shoemaker-Levy collision with Jupiter, the envelopes and photospheres of late-type stars including brown dwarfs, diffuse and translucent clouds, and external galaxies ranging from the nearby Magellanic Clouds to distant quasar absorption line systems and starburst galaxies at the edge of the Universe.
Vividly and in some depth retraces the golden years of particle physics as witnessed by one of the scientists who made seminal contributions to the understanding of what is now known as the Standard Model of particle physics. It will provide the interested reader with a first-hand account and deeper understanding of the multilayered and sinous development that finally led to the present architecture of this theory. Combines particle physics with insightful stories about fellow physicists of some note and the political turmoil of his times.
The experimental and theoretical investigation of nuclei far from the valley of beta-stability is the main subject of modern nuclear structure research. Although the most successful nuclear structure models are purely phenomenological, they nevertheless exploit basic properties of QCD at low energies. This book focuses on the current efforts to bridge the gap between phenomenology and the principles derived from QCD using the extended density functional approach which is based on the successful DFT methods to tackle similarly complex interacting systems in molecular and condensed matter physics. Conceived as a series of pedagogical lectures, this volume addresses researchers in the field as well as postgraduate students and non-specialized scientists from related areas who seek a high-level but accessible introduction to the subject.
Atomic Multielectron Processes is the first comprehensive collection of the data (mostly cross sections and methods) devoted to the multielectron transitions in atoms and ions induced by single collisions with charged particles and photons. The book covers the fundamental ranges of atomic physics which helps understanding the nature of many particle transitions.
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.
The 11th International Conference on X-Ray Lasers had contributions in the following topical areas: Transient Collisional X-Ray Lasers, Table-Top High Repetition Rate X-Ray Lasers, Optical-Field Ionised (OFI) X-Ray Lasers, Theory and Simulation of X-Ray Lasers, High Order Harmonic Generation, XUV Optics and X-Ray Laser Applications, Capillary Discharge X-Ray Lasers, Alternative Sources of coherent XUV Radiation. The proceedings of this conference constitute a comprehensive source of reference for scientists involved in researching the development and application of coherent X-Ray sources.
This book discusses the interaction of light with atoms, concentrating on the semiclassical descriptions of the processes. It begins by discussing the classical theory of electromagnetic radiation and its interaction with a classical charged dipole oscillator. Then, in a pivotal chapter, the interaction with a free charge is described (the Compton effect); it is shown that, in order to give agreement with observation, certain quantum rules must be introduced. The book then proceeds to discuss the interaction from this point of view-light always being described classically, atoms described quantum-mechanically, with quantum rules for the interaction. Subsequent chapters deal with stimulated emission and absorption, spontaneous emission and decay, the general problem of light stimulating and being scattered from the two-state atom, the photoelectric effect, and photoelectric counting statistics. Finally the author gives a personal view on the nature of light and his own way of looking at certain paradoxes. The writing of this book was originally conceived as a collaboration between the present author and a colleague of former years, Alan V. Durrant. Indeed, some preliminary exchange of ideas took place in the mid-1970s. But the problems of joint-authorship from antipodean positions proved too difficult and the project was abandoned. I would like to record my indebted ness to him for the stimulation of this early association. I also acknowledge the encouragement of my colleagues at the Univer sity of Otago. Special reference must be made to D. M."
Electron and Photon Impact Ionisation and Related Topics 2002 provides an overview of recent international research in the field of ionization by electron and photon impact. Emphasizing multi-particle coincidence studies, such as (e,2e), (e,3e), ionization-excitation, and double photo-ionization, the book contains 18 contributions of recent experimental, theoretical, and computational achievements in the realization, interpretation, and modeling of correlated processes that involve a wide range of targets, including atoms, molecules, and surfaces. It also covers nuclear reactions and interaction of electrons, photons, and ions with biological matter. This book is an essential reference for researchers working in atomic and molecular physics, surface science, chemistry, and biophysics.
Soft X-rays are a powerful probe of matter. They interact selectively with electrons in atoms and molecules and can be used to study atomic physics, chemical reactions, surfaces and solids, and biological entities. Over the past 20 years, synchrotrons have emerged as powerful sources of soft X-rays for experimental use. A new, third generation of synchrotron light sources is scheduled to start operation over the next few years, beginning in 1993. These facilities are distinguished by their ultra-low emittance electron beams and by their undulators - precisely engineered magnetic devices that cause the electrons passing through them to produce highly coherent X-rays and ultraviolet light of unprecedented spectral brightness. The book should prove a useful addition to the library of any scientist who needs information on the world's most advanced imaging and spectroscopic techniques.
This book describes the forcefields/interatomic potentials that are used in the atomistic-scale and molecular dynamics simulations. It covers mechanisms, salient features, formulations, important aspects and case studies of various forcefields utilized for characterizing various materials (such as nuclear materials and nanomaterials) and applications. This book gives many help to students and researchers who are studying the forcefield potentials and introduces various applications of atomistic-scale simulations to professors who are researching molecular dynamics.
Discusses the wide range of chemistry in astronomical environments with an emphasis on the description of molecular processes that critically influence the nature and evolution of astronomical objects and the identification of specific observations that directly address significant astronomical questions. The subject areas of the symposium included atomic and molecular processes at low and high temperatures and photon interactions, the chemical structure of molecular clouds in the Milky Way and in external galaxies, the chemistry of outflows and their interactions with the interstellar medium, the chemical connections between the interstellar medium, and the solar system and pregalactic chemistry.
Selected modern aspects of artificially layered structures and bulk materials involving antiferromagnetic long-range order are the main themes of this book. Special emphasis is laid on the prototypical behavior of Ising-type model systems. They play a crucial role in the field of statistical physics and, in addition, contribute to the basic understanding of the exchange bias phenomenon in MBE-grown magnetic heterosystems. Throughout the book, particular attention is given to the interplay between experimental results and their theoretical description, ranging from the famous Lee-Yang theory of phase transitions to novel mechanisms of exchange bias.
Particle production is an important topic in nuclear and particle physics. At high energies, particle production is considered to proceed via parton branching and subsequent fragmentation into hadrons. The study of the dynamics of this process and the study of the structure of hadrons in the context of quantum chromodynamics (QCD) belong to the challenges of the standard model of elementary particle physics, requiring new, nonperturba tive approaches in field theory. Within a nucleus, many-body dynamics is important and particle production may be used to determine many features of a non-equilibrium quantum system at low or high temperatures. At this Advanced Study Institute the different aspects of particle pro duction were expanded upon in a series of lectures given by experts in their fields, covering topics ranging from near-threshold meson production in proton-proton collisions to correlations in multi-GeV jet fragmentation in high-energy scattering processes and signals of a quark-gluon plasma formed in ultra-relativistic heavy-ion collisions. Strong emphasis was placed not only on state of the art research, but also on the necessary physics back ground. The lectures were supplemented by problem sets and discussion sessions. There was also time for students to present short contributions on their research."
