  • Electronic Phase Transitions

    • 1 Edición
    • Volumen 32
    • Yu.V. Kopaev + 1 más
    • Inglés
    Electronic Phase Transitions deals with topics, which are presently at the forefront of scientific research in modern solid-state theory. Anderson localization, which has fundamental implications in many areas of solid-state physics as well as spin glasses, with its influence on quite different research activities such as neural networks, are two examples that are reviewed in this book. The ab initio statistical mechanics of structural phase transitions is another prime example, where the interplay and connection of two unrelated disciplines of solid-state theory - first principle electronic structure calculations and critical phenomena - has given rise to impressive new insights. Clearly, there is more and more need for accurate, stable numerical simulations of models of interacting electrons, presently discussed with great vigor in connection with high-Tc superconductors where the superconducting transition is close to a magnetic transition, i.e. an antiferromagnetic spin structure. These topics and others are discussed and reviewed by leading experts in the field.

    • Peter Hobbs
    • Inglés
    Clouds: Their Formation, Optical Properties, and Effects deals with the formation of clouds as well as the theoretical and experimental aspects of their microphysical and optical properties. Discussions are grouped under the headings of structure of clouds, interaction of passive radiation with clouds, and interaction of active radiation with clouds. This book is organized into three sections and has 11 chapters. After analyzing the spatial and temporal scales involved in the formation and organization of clouds and precipitation, this text examines the microphysical measurement techniques used in probing the microstructure of clouds. The reader is then methodically introduced to the microstructure of atmospheric clouds and precipitation; the formation and structure of fog; and basic shortwave characteristics of “ideal” clouds. The temporal behavior of clouds and their interaction with the radiation field are considered, along with the possible effects of cloud models in general circulation studies. The remaining chapters explore the light scattering properties of ice crystals and the radiative characteristics of ice clouds; the laser measurements in clouds; the transmission and reflectivity of ice clouds by active probing; and the theory of multiple scattering of laser beams in clouds. The book concludes by presenting the measurements of the temporal and spatial spreading of a blue-green pulse through clouds and fogs as a function of optical thickness and receiver field-of-view. This text will be helpful to advanced researchers and program managers in terms of reviewing the state of the art and identifying those areas requiring further research efforts.

    • Ivo Slaus
    • Inglés
    Few Particle Problems in the Nuclear Interaction emerged from the International Conference on Few Particle Problems in the Nuclear Interaction held in Los Angeles, from August 28-September 1, 1972. The aim of the conference was to discuss recent developments in low and medium energy few-particle problems. This included the fields of the nuclear three-body problem; nuclear forces (in particular, three-body forces); symmetries; and the interaction of mesons, leptons, and photons with few-nucleon systems. Special sessions were also devoted to the application of the results and techniques of the few-particle research to the problems of other fields, in particular nuclear structure and astrophysics. The conference was organized into nine plenary sessions and 13 parallel sessions. This volume contains 184 papers presented during the nine sessions on the following topics: the nucleon-nucleon interaction; three-body forces; hypernuclear systems; symmetries; three-body problems; multiparticle reactions; proposed studies of few-nucleon systems with meson factories; few-nucleon systems and leptons, mesons, and photons; and applications.

  • Inflation and Quantum Cosmology

    • 1 Edición
    • A.D. Linde
    • Inglés
    Inflation and Quantum Cosmology discusses the inflationary universe scenario, including the problems of the standard big bang theory and the interplay between elementary-particle theory and cosmology. Inflationary universe models generate many different final perturbation spectra. For example, a model of an inflationary universe, through a casual mechanism, can predict energy density fluctuations leading to the formation of galaxies. The inflationary universe scenario makes possible simultaneous solutions to ten problems related to cosmology and elementary particle physics. One problem concerns the origin of density perturbations that show a picture of the large-scale structure of the universe. Some unexplored possibilities are related to isothermal perturbations generated during inflation or to adiabatic perturbations with a non-flat spectrum. An inflationary universe cosmology also includes stochastic inflation that describes the universe on very large scales—from fragmented mini-universes to another inflationary cosmos. The book also discusses the problem relating to the initial conditions from which an inflationary universe starts. This book is suitable for astronomers, astrophysicists, and professors of cosmology and cosmogenesis.

  • Unidirectional Wave Motions

    • 1 Edición
    • Volumen 23
    • H. Levine
    • Inglés
    Unidirectional Wave Motions provides a comprehensive discussion of the formulations and their consequent elaborations which have found demonstrable value in wave analysis. The deliberate focus on unidirectional waves permits a relatively simple mathematical development, without leaving significant gaps in methodology and capability. The book is organized into three parts. The first part deals with the particulars of individual wave equations; the geometry or kinematics of wave forms; and general matters bearing on the transport of energy and momentum as well as dispersion or frequency sensitivity. The second part focuses on aspects of wave generation by localized and extended sources. The third part examines the effects of interaction between specified primary waves and medium irregularities (e.g., obstacles, inclusions, or local variations in the material parameters). Information about these irregularities or scatterers, ranging from microscopic to terrestrial scales, may be gleaned through the attendant phenomena of reflection, refraction, and diffraction, which are fundamental to wave theory.

  • Atomic Collisions and Spectra

    • 1 Edición
    • U Fano
    • Inglés
    Atomic Collisions and Spectra provides an overview of the state of knowledge on atomic collision physics. The book grew out of lecture notes for a succession of courses at the University of Chicago in 1967-1979, which reported the new material as it was taking a definite form. It has been enriched since 1980, as the subject matured and continued to expand. The book is organized into four parts. Part A deals briefly with rather elementary items of general information. Part B then takes up in considerable detail those aspects of single-electron scattering whose mastery is essential for treating multielectron processes. Part C deals with multielectron processes with a residual—if often realistic—restrictio... namely, that the multielectron interactions remain confined within a core region from which only a single electron escapes into alternative channels of a long-range field. Part D surveys studies of double (or multiple) escape of electrons from a core. The book is intended for multiple use as a graduate school text, a tool for independent study, or a reference for particular topics.

Chapter 1 deals with infrared data processing techniques. Chapter 2 concerns itself with circular dichroism*b1FT-IR. Chapter 3 presents an update on GC*b1FT-IR, a rapidly moving field. Chapter 4 deals with the combination of FT-IR and thermal analysis. Advances in coal analyses using FT-IR are presented in Chapter 5. Reflectance studies are highlighted in Chapters 6, 7, and 8. Chapter 6 deals with structural characterizations made with Langmuir*b1Blodgett monolayers. Also in Chapter 6, the extension of DRIFT into the far-infrared region is shown to be feasible and valuable. Reflection*b1absorpt... surface studies (FT-IRRAS) are discussed in Chapter 8. Chapter 9 updates us on photoacoustic spectroscopy*b1FT-IR... of the contributions are made by working experts in these areas. It is the hope that Volume 4 continues in the spirit of the purpose of these volumes, namely, to keep the scientific communities abreast of new developments in FT-IR as applied to chemical systems.

  • Kapitza in Cambridge and Moscow

    Life and Letters of a Russian Physicist
    • 1 Edición
    • J.W. Boag + 2 más
    • Inglés
    The unusual career of the famous Soviet physicist Peter Kapitza was divided between Cambridge and Moscow. In Cambridge he was a protegé of Rutherford and while studying there he opened up a new area of research in magnetism and low temperature physics. However, in 1934, during a summer visit to the Soviet Union, Kapitza was prevented from returning to Cambridge and remained in Moscow for the rest of his long life. In spite of many ups and downs and considerable difficulties in his relations with top political figures in the Kremlin, he continued to enhance his scientific reputation and late in life was awarded the Nobel Prize.After an introductory biographical memoir, the greater part of the book consists of extracts from the numerous letters Kapitza wrote throughout his life, letters which are distinguished by their eloquence, the originality of his opinions and his forthrightness. His very interesting correspondence with Rutherford and above all his many letters to top political figures in the Soviet Union such as Molotov, Stalin and Khrushchev on questions of scientific and industrial policy are all included in this unique document. Together they provide a rounded picture of a remarkable personality who contributed so much to the scientific and cultural life of both England and the Soviet Union.This fascinating book is illustrated with an impressive collection of historical photographs and should be of interest to science historians, to low temperature physicists and to `Sovietologists', but above all the book should appeal to the general reader for its human interest. Some of the letters reveal his emotional reactions to the major blows he had to suffer on several occasions, while others provide penetrating and often amusing comments on English life and institutions as seen by a Russian, and on Soviet life from the inside.

  • High Pressure Phase Behaviour of Multicomponent Fluid Mixtures

    • 1 Edición
    • R.J. Sadus
    • Inglés
    The high pressure phase behaviour of binary fluid mixtures has been extensively studied during the last three decades. There is ample experimental data for a wide variety of binary mixtures and extensive methods for prediction have been developed. In contrast, the investigation of ternary and other multicomponent fluids is in its infancy. Experimental ternary mixture critical data are very rare and theoretical studies have been limited to data correlation rather than genuine prediction. The phase behaviour of ternary and other multicomponent fluid mixtures has many novel aspects which are not manifested in binary mixtures. The properties of ternary mixtures are also likely to be more difficult to characterize experimentally. It is in this context that calculated phase diagrams have an important role in leading the discovery of new phenomena and guiding experimental work.The criteria for phase equilibria of multicomponent fluids with particular emphasis on the critical state are examined in this book, and models for predicting fluid equilibria (e.g., different equations of state) are compared. Particular attention is paid to the critical state of ternary mixtures which has hitherto been largely neglected. The problems associated with predicting ternary equilibria are discussed, and some novel aspects of ternary critical phenomena are illustrated. The books also describes a novel type of critical transition which appears to be a common feature of the equilibria of ternary mixtures. Extensive phase diagrams of a wide range of ternary mixtures including systems containing carbon dioxide, water, nitrogen and tetrafluoromethane as one or more component are presented. The theoretical treatment is detailed in the appendix and a computation of known experimental critical points is also included.

    Over the past few years, finite-size scaling has become an increasingly important tool in studies of critical systems. This is partly due to an increased understanding of finite-size effects by analytical means, and partly due to our ability to treat larger systems with large computers. The aim of this volume was to collect those papers which have been important for this progress and which illustrate novel applications of the method. The emphasis has been placed on relatively recent developments, including the use of the &egr;-expansion and of conformal methods.

    H.B.G. Casimir's life, interests and works are intertwined with the importantdevelopment... that have taken place in physics during this century. This book was compiled by his friends and admirers in honour of his 80th birthday andconcentrates mainly on Casimir's achievements in the field of physics, thoughwithout ignoring the peripheral areas of the history and philosophy of physics in which he was greatly interested. The book is divided into four parts. Part I describes Casimir's teachers, Ehrenfest, Bohr and Pauli, and will be of general interest due to the key role which these physicists played in moderndevelopments. The articles do give new facts and provide new insights into thehistory of modern physics. Part II consists of essays on recent developments invarious areas of physics in which Casimir has taken an active interest, such asthe modern concept of time, statistical foundations of electrodynamic theory andfield theory. The subjects covered in Part III have been selected because ofCasimir's efforts in the industrial research area of physics. They cover past,present and future expectations in research. Part IV contains an essay whichdiscusses a philosophy of physics currently under discussion, which states thatphenomenological laws prevail over fundamental ones for the purpose ofexperimental and technical physics. A second chapter in this final part gives acritical analysis of this philosophical view. The book is concluded by anappendix discussing Casimir's activities as a lecturer, written by a formerstudent.

    • Inglés
    Recent Research in Molecular Beam is a collection of scientific papers that have been inspired by Otto Stern, the founder of Molecular Beam Research. This book is composed of 10 chapters and begins with discussions on the early history of molecular beam research. The next chapters describe the velocity distribution measurements made on potassium molecular beams with a fixed-frequency, variable phase velocity selector, along with a brief consideration of the principles and concepts of electron magnetic moment and atomic magnetism. A chapter presents the atomic beam spectroscopic experiments on the metastable state of the hydrogen-like atoms that depend on a wholly different principle for the detection of transitions. This text further explores the effects of variations in the oscillatory field amplitudes, perturbations by neighboring resonances, perturbations by oscillatory fields, variations in the fixed field amplitudes, and phase shifts of the oscillatory fields. These topics are followed by a comparison of advantages and limitations of various techniques for spin property measurement as they apply in particular to radioactive nuclei, such as optical and molecular gas microwave spectroscopy, nuclear and paramagnetic resonance, and atomic beams. The remaining chapters examine fluid friction in a rarefied gas flow; some applications of molecular beam techniques to chemistry; and the polarized neutrons based on a Stern-Gerlach experiment. This work will be of great value to workers and researchers in molecular beam field.

    • Inglés
    Physical Acoustics: Principles and Methods, Volume IX includes four chapters that are device-oriented and devoted to understanding electron drag stresses on dislocations and difference in flow stress between the normal and superconducting states of Type I and Type II superconductors. Chapter 1 explains that when a dislocation moves through a crystal, it gives up energy to the medium either through a nonlinear motion over a dynamic Peierls barrier or through conversion of energy by scattering of electrons or phonons, which takes place with an energy loss proportional to the velocity. The next chapter discusses the propagation of ultrasonic surface waves in thin layers. The thin layer confines a surface wave laterally, providing a desired dispersion characteristic, acting as part of a transducer for generating surface waves, or providing an interaction region for other phenomena. Chapter 3 deals with a generation of solid state control elements that utilize the inverse piezoelectric effect. The last chapter provides approximate equations for coupled resonators and methods for accurately controlling the band frequency and bandwidth. This book is a useful reference for students and physicists working on physical acoustics.
