This book reports on the latest developments in the field of Superfluidity. The phenomenon has had a tremendous impact on the fundamental sciences as well as a host of technologies. It began with the discovery of superconductivity in mercury in 1911, which was ultimately described theoretically by the theory of Bardeen Cooper and Schriever (BCS) in 1957. The analogous phenomena, superfluidity, was discovered in helium in 1938 and tentatively explained shortly thereafter as arising from a Bose-Einstein Condensation (BEC) by London. But the importance of superfluidity, and the range of systems in which it occurs, has grown enormously. In addition to metals and the helium liquids the phenomena has now been observed for photons in cavities, excitons in semiconductors, magnons in certain materials, and cold gasses trapped in high vacuum. It very likely exist for neutrons in a neutron star and, possibly, in a conjectured quark state at their center. Even the Universe itself can be regarded as being in a kind of superfluid state. All these topics are discussed by experts in the respective subfields.
Heinz offers wise answers to questions about death, urging readers to "recover a death of [their] own" and to view the final years as a fulfillment, a "last career".
This book treats the central physical concepts and mathematical techniques used to investigate the dynamics of open quantum systems. To provide a self-contained presentation the text begins with a survey of classical probability theory and with an introduction into the foundations of quantum mechanics with particular emphasis on its statistical interpretation. The fundamentals of density matrix theory, quantum Markov processes and dynamical semigroups are developed. The most important master equations used in quantum optics and in the theory of quantum Brownian motion are applied to the study of many examples. Special attention is paid to the theory of environment induced decoherence, its role in the dynamical description of the measurement process and to the experimental observation of decohering Schrodinger cat states. The book includes the modern formulation of open quantum systems in terms of stochastic processes in Hilbert space. Stochastic wave function methods and Monte Carlo algorithms are designed and applied to important examples from quantum optics and atomic physics, such as Levy statistics in the laser cooling of atoms, and the damped Jaynes-Cummings model. The basic features of the non-Markovian quantum behaviour of open systems are examined on the basis of projection operator techniques. In addition, the book expounds the relativistic theory of quantum measurements and discusses several examples from a unified perspective, e.g. non-local measurements and quantum teleportation. Influence functional and super-operator techniques are employed to study the density matrix theory in quantum electrodynamics and applications to the destruction of quantum coherence are presented. The text addresses graduate students and lecturers in physics and applied mathematics, as well as researchers with interests in fundamental questions in quantum mechanics and its applications. Many analytical methods and computer simulation techniques are developed and illustrated with the help of numerous specific examples. Only a basic understanding of quantum mechanics and of elementary concepts of probability theory is assumed.

Further, it picks up on hot topics in current research, like quantum structures, mono-layer semiconductors or Perovskites. The experimental aspects of semiconductor optics are complemented by an in-depth discussion of group theory in solid-state optics. Covering subjects ranging from physics to materials science and optoelectronics, this book provides a lively and comprehensive introduction to semiconductor optics. With over 120 problems, more than 480 figures, abstracts to each chapter, as well as boxed inserts and a detailed index, it is intended for use in graduate courses in physics and neighboring sciences like material science and electrical engineering. It is also a valuable reference resource for doctoral and advanced researchers.
Here, for the first time in English, is an illuminating German perspective on the decisive blitzkrieg campaign. The account, written by the German historian Karl-Heinz Frieser and edited by American historian John T. Greenwood, provides the definitive explanation for Germany’s startling success and the equally surprising military collapse of France and Britain on the European continent in 1940. In a little over a month, Germany defeated the Allies in battle, a task that had not been achieved in four years of brutal fighting during World War I. First published in 1995 as the official German history of the 1940 campaign, this book goes beyond standard explanations to show that the German victory was not inevitable and that French defeat was not preordained. Contrary to most accounts of the campaign, Frieser’s illustrates that the military systems of both Germany and France were solid and that their campaign plans were sound. The key to victory or defeat, Frieser argues, was the execution of operational plans—both preplanned and ad hoc—amid the eternal Clausewitzian combat factors of friction and the fog of war. He shows why, on the eve of the campaign, the British and French leaders had good cause to be confident and why many German generals were understandably concerned that disaster was looming for them. This study explodes many of the myths concerning German blitzkrieg warfare and the planning for the 1940 campaign. Frieser’s groundbreaking interpretation of the topic has been the subject of discussion since the German edition first appeared. This English translation is published in cooperation with the Association of the United States Army.
This monograph is concerned with the III-V bulk and low-dimensional semiconductors, with the emphasis on the implications of multi-valley bandstructures for the physical mechanisms essential for opto-electronic devices. The optical response of such semiconductor materials is determined by many-body effects such as screening, gap narrowing, Fermi-edge singularity, electron-hole plasma and liquid formation. Consequently, the discussion of these features reflects such interdependencies with the dynamics of excitons and carriers resulting from intervalley coupling.
Interactions between Electromagnetic Fields and Matter deals with the principles and methods that can amplify electromagnetic fields from very low levels of signals. This book discusses how electromagnetic fields can be produced, amplified, modulated, or rectified from very low levels to enable these for application in communication systems. This text also describes the properties of matter and some phenomenological considerations to the reactions of matter when an action of external fields results in a polarization of the particle system and changes the bonding forces existing in the matter. This book considers the above phenomena in detail by explaining matter as a conglomeration of charged mass points in the electromagnetic field. Quantum mechanics and Maxwell's theory can then account for the precise description of the interactions between the electromagnetic fields and matter. This book then describes special processes such as 1) the static and quasistatic interactions and 2) dynamic processes, particularly the resonance process. This text also defines a general form for electric and magnetic reactions using the generalized field equation. This book also cites the anharmonic oscillator and the single spin as different examples of electric and magnetic dipole interactions. This text is suitable for electrical engineers, radio technicians, physicists whose work is in quantum mechanics, and engineers interested in electro-magnetism theory.

The first advanced textbook to provide a useful introduction in a brief, coherent and comprehensive way, with a focus on the fundamentals. After having read this book, students will be prepared to understand any of the many multi-authored books available in this field that discuss a particular aspect in more detail, and should also benefit from any of the textbooks in photochemistry or spectroscopy that concentrate on a particular mechanism. Based on a successful and well-proven lecture course given by one of the authors for many years, the book is clearly structured into four sections: electronic structure of organic semiconductors, charged and excited states in organic semiconductors, electronic and optical properties of organic semiconductors, and fundamentals of organic semiconductor devices.
This book treats the physics of Electron Loss Spectroscopy (ELS) with electrons of different energies. Its emphasis is on the collective excitations or plasmons in the bulk as well as on the surface, including interaction with the interband transitions. A discussion of the experimental and theoretical aspects helps to define the current state of the art. In addition to the general physics, data on the plasmons (energy, halfwidth, dispersion) obtained by different methods of observation (transmission and reflection with fast and slow electrons) have been collected as completely as possible. Mr. R. Manzke was helpful in gathering these figures. Related topics such as coupling of plasmons with light, Cerenkov radiation and waveguides, plasmons in electron gases of one and two dimensions together with some applications (microanalysis) are briefly described to round off the representation and to demonstrate the usefulness of the plasmon concept."--Preface
