Synopsis Semiclassical Approach to Mesoscopic Systems by : Daniel Waltner

This volume describes mesoscopic systems with classically chaotic dynamics using semiclassical methods which combine elements of classical dynamics and quantum interference effects. Experiments and numerical studies show that Random Matrix Theory (RMT) explains physical properties of these systems well. This was conjectured more than 25 years ago by Bohigas, Giannoni and Schmit for the spectral properties. Since then, it has been a challenge to understand this connection analytically. The author offers his readers a clearly-written and up-to-date treatment of the topics covered. He extends previous semiclassical approaches that treated spectral and conductance properties. He shows that RMT results can in general only be obtained semiclassically when taking into account classical configurations not considered previously, for example those containing multiply traversed periodic orbits. Furthermore, semiclassics is capable of describing effects beyond RMT. In this context he studies the effect of a non-zero Ehrenfest time, which is the minimal time needed for an initially spatially localized wave packet to show interference. He derives its signature on several quantities characterizing mesoscopic systems, e. g. dc and ac conductance, dc conductance variance, n-pair correlation functions of scattering matrices and the gap in the density of states of Andreev billiards.

Synopsis Semiclassical Theory of Mesoscopic Quantum Systems by : Klaus Richter

This book describes manifestations of classical dynamics and chaos in the quantum properties of mesoscopic systems. During the last two decades mesoscopic physics has evolved into a rapidly progressing and exciting interdisciplinary field of physics. The first part of the book deals with integrable and chaotic classical dynamics with particular emphasis on the semiclassical description of spectral correlations, thermodynamic properties and linear response functions. The main part shows applications to prominent observables in the mesoscopic context.

Synopsis Introduction to Condensed Matter Physics by : Duan Feng

This is volume 1 of two-volume book that presents an excellent, comprehensive exposition of the multi-faceted subjects of modern condensed matter physics, unified within an original and coherent conceptual framework. Traditional subjects such as band theory and lattice dynamics are tightly organized in this framework, while many new developments emerge spontaneously from it. In this volume,? Basic concepts are emphasized; usually they are intuitively introduced, then more precisely formulated, and compared with correlated concepts.? A plethora of new topics, such as quasicrystals, photonic crystals, GMR, TMR, CMR, high Tc superconductors, Bose-Einstein condensation, etc., are presented with sharp physical insights.? Bond and band approaches are discussed in parallel, breaking the barrier between physics and chemistry.? A highly accessible chapter is included on correlated electronic states ? rarely found in an introductory text.? Introductory chapters on tunneling, mesoscopic phenomena, and quantum-confined nanostructures constitute a sound foundation for nanoscience and nanotechnology.? The text is profusely illustrated with about 500 figures.

Synopsis Complex Phenomena in Nanoscale Systems by : Giulio Casati

Nanoscale physics has become one of the rapidly developing areas of contemporary physics because of its direct relevance to newly emerging area, nanotechnologies. Nanoscale devices and quantum functional materials are usually constructed based on the results of fundamental studies on nanoscale physics. Therefore studying physical phenomena in nanosized systems is of importance for progressive development of nanotechnologies. In this context study of complex phenomena in such systems and using them for controlling purposes is of great practical importance. Namely, such studies are brought together in this book, which contains 27 papers on various aspects of nanoscale physics and nonlinear dynamics.

Synopsis Transport Phenomena in Mesoscopic Systems by : Hidetoshi Fukuyama

This volume contains the proceedings of the Fourteenth Thniguchi Symposium on the Theory of Condensed Matter, which was held from November 10 to 14, 1991, at the Shima Kanko Hotel, Shima, Japan. The topic of the symposium was Physics 0/ Mesoscopic Systems. Mesoscopic systems have been developed band in band with the recent progress in nanotechnology and are the melting pot of basic science and technology. In nanostructures, the quantum effect of the electron wave manifests itself because of the limited dimensionality of the structure. The most typical features of these structures are the discreteness of the energy spectrum and the interference effect of electron waves, which have led to various fascinating phenomena. The purpose of this symposium was to discuss the latest developments in mesoscopic systems, especially transport phenomena, from the viewpoint of basic physics. This volume starts with an introduction to the field of mesoscopic systems together with the paper by Prof. R. Kubo, who was the first to note the existence of particular features of discrete energy levels in small metallic particles. In Part II the electronic states of quantum dots and the conductance through them are discussed. Tunneling via small structures and junctions is studied in Part ill.
