Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Deep Inelastic Positron Proton Scattering in the High Momentum Transfer Regime of HERA written by Ulrich F. Katz and published by Springer Science & Business Media. This book was released on 2000-09-04 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: About three decades after the first experiments on deep inelastic lepton hadron scattering began to investigate the structure of hadrons, the history of this fruitful field of particle physics continues in the broad spectrum of research performed at the electron and positron proton collider HERA at DESY, where the multipurpose detectors ZEUS and H1 access ep scattering at a center of mass energy of 300 GeV and explore as yet uncharted kinematic realms of deep inelastic scattering. After the first years of data taking at HERA, each of the experiments has collected a total of roughly 40 pb 1 of e+p data, yielding sensitivity to deep inelastic e+p interactions at high four momentum transfers, Q2, where typi cal cross sections drop into the subpicobarn regime. This kinematic domain is characterized by electroweak unification, manifesting itself most markedly in the neutral and charged current cross sections, which approach an equal order of magnitude as Q2 rises above the square of the W and Z masses. Consequently, HERA allows, for the first time, studies of both types of pro cesses simultaneously with the same initial state conditions and in the same detector, and thus we can investigate the interplay of electroweak and strong forces governing the respective cross sections.
Download or read book Electron Beam Interactions with Solids written by Maurizio Dapor and published by Springer Science & Business Media. This book was released on 2003-04-23 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of electron beams with solid targets has been studied since the early part of the last century. Present interest is spurred on by the fundamental role played by the electron-solid interaction in - among other areas - scanning electron microscopy, electron-probe microanalysis and Auger electron spectroscopy. This book aims to investigate selected aspects of the interaction of electrons with matter (backscattering coefficient for bulk targets, absorption, backscattering and transmission for supported and unsupported thin films, implantation profiles, secondary electron emission and so on); to study the probabilistic laws of interaction of the individual electrons with the atoms (elastic and inelastic cross sections); to introduce the Monte Carlo method and its use for computing the macroscopic characteristics of the interaction processes. Each chapter compares theory, simulations and experimental data.
Download or read book Transmission Electron Microscopy of Semiconductor Nanostructures written by Andreas Rosenauer and published by Springer Science & Business Media. This book was released on 2003-02-13 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides tools well suited for the quantitative investigation of semiconductor electron microscopy. These tools allow for the accurate determination of the composition of ternary semiconductor nanostructures with a spatial resolution at near atomic scales. The book focuses on new methods including strain state analysis as well as evaluation of the composition via the lattice fringe analysis (CELFA) technique. The basics of these procedures as well as their advantages, drawbacks and sources of error are all discussed. The techniques are applied to quantum wells and dots in order to give insight into kinetic growth effects such as segregation and migration. In the first part of the book the fundamentals of transmission electron microscopy are provided. These are needed for an understanding of the digital image analysis techniques described in the second part of the book. There the reader will find information on different methods of composition determination. The third part of the book focuses on applications such as composition determination in InGaAs Stranski--Krastanov quantum dots. Finally it is shown how an improvement in the precision of the composition evaluation can be obtained by combining CELFA with electron holography. This is demonstrated for an AlAs/GaAs superlattice.
Download or read book Emulsion Science written by Jerôme Bibette and published by Springer. This book was released on 2003-07-01 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emulsions occur either as end products or during the processing of products in a huge range of areas including the food, agrochemical, pharmaceuticals, paints and oil industries. As end products, emulsions allow to avoid organic solvent in processing hydrophobic coatings. Emulsion technology is a suitable approach to vehicle viscous phases. It is also a remarkable mean of targeting actives or capturing specific species. The range of applications of emulsions progresses and their manufacturing becomes more and more sophisticated. Besides this broad domain of technological interest, emulsions are raising a variety of fundamental questions at the frontier between physic and chem istry. Indeed, as a class of soft colloidal materials, emulsions science is linked to various aspects of these disciplines: phase transitions, surface forces and wetting, metastability and hydrodynamic instabilities, mechanical properties and flow. The aim of this book is to review the main important concepts governing emulsion science. In Chapter 2, repulsive interactions between liquid films are discussed as well as adhesive interaction related to wetting. In Chap ter 3, consequences of weak and strong attractions are presented, related to the well accepted liquid solid transition analogy. In Chapter 4, the basics of both bulk compressibility and shear elasticity are presented, the role of disorder being the most important aspect of the elastic behavior of these soft systems. In Chapter 5 the central question of the emulsion lifetime related to metastability is discussed.

Download or read book Cold and Ultracold Collisions in Quantum Microscopic and Mesoscopic Systems written by John Weiner and published by Cambridge University Press. This book was released on 2003-12-04 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cold and ultracold collisions occupy a strategic position at the intersection of several powerful themes of current research in chemical physics, in atomic, molecular and optical physics, and even in condensed matter. The nature of these collisions has important consequences for optical manipulation of inelastic and reactive processes, precision measurement of molecular and atomic properties, matter-wave coherences and quantum-statistical condensates of dilute, weakly interacting atoms. This crucial position explains the wide interest and explosive growth of the field since its inception in 1987. The author reviews elements of the quantum theory of scattering theory, collisions taking place in the presence of one or more light fields, and collisions in the dark, below the photon recoil limit imposed by the presence of any light field. Finally, it reviews the essential properties of these mesoscopic quantum systems and describes the key importance of the scattering length to condensate stability.
