This volume includes papers from 1887, when Lord Rayleigh became Professor of Natural Philosophy at the Royal Institution in London, to 1892. An 1888 contribution on the densities of hydrogen and oxygen led to a series of experiments on the densities of the atmospheric gases. This resulted in the unsettling discovery that the density of atmospheric nitrogen seemed very slightly to exceed the density of nitrogen derived from its chemical compounds. A substantial 1888 paper, on the wave theory of light, was written for the Encyclopaedia Britannica in the immediate aftermath of the crucial Michelson–Morley experiment in which the speed of light had been measured. In addition, this wide-ranging volume shows Rayleigh's developing interest in the properties of liquid surfaces, with a discourse on foams (1890), and a paper on surface films (1892). It also includes a charming brief appreciation (1890) of James Clerk Maxwell's legacy to science.
This book shows how the concept of geometrical frustration can be used to elucidate the structure and properties of non-periodic materials such as metallic glasses, quasicrystals, amorphous semiconductors and complex liquid crystals. Geometric frustration is introduced through examples and idealized models, leading to a consideration of how the concept can be used to identify ordered and defective regions in real materials. Then it is shown how these principles can also be used to model physical properties of materials, in particular specific volume, melting, the structure factor and the glass transition. Final chapters consider geometric frustration in periodic structures with large cells and quasiperiodic order. Appendices give all necessary background on geometry, symmetry and tilings. The text considers geometrical frustration at different scales in many types of materials and structures, including metals, amorphous solids, liquid crystals, amphiphiles, cholisteric systems, polymer
Bose-Einstein condensation of excitons is a unique effect in which the electronic states of a solid can self-organize to acquire quantum phase coherence. The phenomenon is closely linked to Bose-Einstein condensation in other systems such as liquid helium and laser-cooled atomic gases. This is the first book to provide a comprehensive survey of this field, covering theoretical aspects as well as recent experimental work. After setting out the relevant basic physics of excitons, the authors discuss exciton-phonon interactions as well as the behaviour of biexcitons. They cover exciton phase transitions and give particular attention to nonlinear optical effects including the optical Stark effect and chaos in excitonic systems. The thermodynamics of equilibrium, quasi-equilibrium, and nonequilibrium systems are examined in detail. The authors interweave theoretical and experimental results throughout the book, and it will be of great interest to graduate students and researchers in semicon
This 1998 book describes the physics of superconductivity and superfluidity, macroscopic quantum phenomena found in many conductors at low temperatures and in liquid helium 4 and helium 3. In the first part of the book the author presents the mean field theory of generalized pair condensation. This is followed by a description of the properties of ordinary superconductors using BCS theory. The book then proceeds with expositions of strong coupling theory and the Ginzberg-Landau theory. The remarkable properties of superfluid helium 3 are then described, as an example of a superfluid with internal degrees of freedom. The topics covered are dealt with in a coherent manner, with all necessary theoretical background given. Recent topics in the field, such as the copper-oxide high temperature superconductors and exotic superconductivity of heavy fermion systems are discussed in the final chapter. This book will be of interest to graduate students and researchers in condensed matter physics,
An introduction to the properties of wavelike excitations associated with surfaces and interfaces. The emphasis is on acoustic, optic, and magnetic excitations, and, apart from one section on liquid surfaces, the text concentrates on solids. The important topic of superlattices is also discussed, in which the different kinds of excitation are considered from a unified point of view.
This book describes the various methods currently used to deposit highly ordered organic films, and the physical techniques employed in characterising their properties. Such films are the subject of a great deal of research, motivated by their potential application in micro-electronics. Beginning with a discussion of the necessary basic physics and chemistry, the book proceeds to a description of the main topics of current research in this field. The Langmuir–Blodgett technique, self-assembly, and methods of film deposition exploiting the ordered structure of mesophases are described in detail. Liquid crystals, films at the air/water interface and biomembranes are also discussed. The book is aimed at those graduate students and established research workers with an interest in the physics and chemistry of these fascinating structures.
This book is aimed at scientists and engineers wanting to use radioisotopes and the emitted ionising radiations competently but without seeking expertise. It describes decay and stability criteria, necessary precautions to ensure radiation protection and the detection of alpha, beta and gamma rays including spectrometry. There are comments on calorimetry, liquid scintillation counting, how to use secondary standard instruments, high resolution detectors and how to calculate counting results estimating uncertainties and allowing for the statistics of radionuclide decays. The book's principal purpose is to encourage radionuclide applications which can be done safely, reliably and accurately. It describes industrial and scientific applications of alpha, beta, and gamma rays, neutrons and high energy radiations. This book will be of particular interest to scientists and technologists, teachers and students, helping them to work with radioisotopes safely, efficiently and reliably.
There are a variety of models which can be used to study nuclear structure and dynamics. This book gives a comprehensive overview of these various models, concentrating in particular on a description of deformed and rotating nuclei. Following a treatment of the semi-empirical mass formula and nuclear stability, the liquid-drop and simple shell models are introduced and described. The spherical nuclear one-particle potential is introduced and developed to cover the case of deformed nuclei. The latter chapters of the book are devoted to discussions of barrier penetration, fast nuclear rotation, nucleon-nucleon interactions and the pairing interaction. Many problems and solutions are included, which help to illustrate key concepts. The book will be invaluable to graduate students of nuclear physics, and to anyone engaged in research in this field.
When many polymers are heated they transform directly into carbons, without passing through an intermediate liquid paste. Such carbons are termed polymetric carbons. Phenolic resins yield an isotropic impervious black glassy carbon which is hard enough to scratch window glass and has interesting electronic properties. polyacrylonitrile fibres yield carbon fibre with enormous stiffness and strength. Combinations of the two produce the strongest carbon material (carbon-fibre-reinforced carbon). Carbon-fibre-reinforced plastics are revolutionary low density-high-stiffness materials. This 1976 book brings together data from the authors' work to describe the manufacture of polymetric carbons. It provides a description of physical, mechanical and chemical properties which are related as closely as possible to the revealed structure. Emphasis is placed on the more interesting aspects, such as development of high-strength, high-stiffness material, the semi-conducting behaviour of intermediate
Now in paperback, this book provides an overview of the physics of condensed matter systems. Assuming a familiarity with the basics of quantum mechanics and statistical mechanics, the book establishes a general framework for describing condensed phases of matter, based on symmetries and conservation laws. It explores the role of spatial dimensionality and microscopic interactions in determining the nature of phase transitions, as well as discussing the structure and properties of materials with different symmetries. Particular attention is given to critical phenomena and renormalization group methods. The properties of liquids, liquid crystals, quasicrystals, crystalline solids, magnetically ordered systems and amorphous solids are investigated in terms of their symmetry, generalised rigidity, hydrodynamics and topological defect structure. In addition to serving as a course text, this book is an essential reference for students and researchers in physics, applied physics, chemistry, m
This book addresses selected aspects of steel-deformation modelling, both at very high temperatures and under the conditions in which the liquid and the solid phases coexist. Steel-deformation modelli
Thermally excited defects such as vortices, disclinations, dislocations, vacancies and interstitials play a key role in the physics of crystals, superfluids, superconductors, liquid crystals and polymer arrays. Geometrical aspects of statistical mechanics become particularly important when thermal fluctuations entangle or crumple extended line-like or surface-like objects in three dimensions. In the case of entangled vortices above the first-order flux lattice melting transition in high temperature superconductors, the lines themselves are defects. A variety of low temperature theories combined with renormalization group ideas are used to describe the delicate interplay between defects, statistical mechanics and geometry characteristic of these problems in condensed matter physics. In this 2002 book, David Nelson provides a coherent and pedagogic graduate level introduction to the field of defects and geometry.
