DOWNLOAD EBOOKThe NATO Advanced Research Workshop took place from 29 May to I June 2000 in the picturesque Hungarian town of Pecs, 220 km south of Budapest. The main goal of the workshop was to review and promote experimental and theoretical research on the problem of Kondo-type scatteringofthe electrons in systems ofreduced dimensionalities. 53 regular participants and 7 observers from 17 different countries attended the workshop. The Kondo effect has been a topic ofintense interest for many years, due in part to its relevance to a variety of other branches of condensed matter physics. In addition to the best known example of magnetic impurities in noble metals, the physics of the Kondo effect is important in many areas of current research, including heavy-fermion physics, correlated electron systems, and high-temperature superconductivity. Of central importance in this problem is the interaction of conduction electrons in the metal with individual magnetic impurities, an interaction which also mediates the interaction ofthe impurities with each other.

DOWNLOAD EBOOKThe last few years have seen many developments in the study of ?frustrated? systems, such as spin glasses and random fields. In addition, the application of the idea of spin glasses to other branches of physics, such as vortex lines in high temperature superconductors, protein folding, structural glasses, and the vulcanization of rubber, has been flourishing. The earlier reviews are several years old, so now is an appropriate time to summarize the recent developments. The articles in this book have been written by leading researchers and include theoretical and experimental studies, and large-scale numerical work (using state-of-the-art algorithms designed specifically for spin-glass-type problems), as well as analytical studies.

DOWNLOAD EBOOKThree scientists from the L.D. Landau Institute of Theoretical Physics, Moscow, review recent developments in the theory of spin glasses and related strongly disordered systems. They discuss in particular the problems of irreversibility and nonergodicity in the framework of the mean field theory, a phase transition in three- dimensional spin glasses, and glass-like systems with hidden correlations. Addressed to researchers in theoretical physics. Book club price $59. Annotation copyrighted by Book News, Inc., Portland, OR

DOWNLOAD EBOOKSpin glasses are disordered magnetic systems that have led to the development of mathematical tools with an array of real-world applications, from airline scheduling to neural networks. Spin Glasses and Complexity offers the most concise, engaging, and accessible introduction to the subject, fully explaining what spin glasses are, why they are important, and how they are opening up new ways of thinking about complexity. This one-of-a-kind guide to spin glasses begins by explaining the fundamentals of order and symmetry in condensed matter physics and how spin glasses fit into--and modify--this framework. It then explores how spin-glass concepts and ideas have found applications in areas as diverse as computational complexity, biological and artificial neural networks, protein folding, immune response maturation, combinatorial optimization, and social network modeling. Providing an essential overview of the history, science, and growing significance of this exciting field, Spin Glasses and Complexity also features a forward-looking discussion of what spin glasses may teach us in the future about complex systems. This is a must-have book for students and practitioners in the natural and social sciences, with new material even for the experts.

DOWNLOAD EBOOKThe electrical properties of mesoscopic AuFe wires have been measured in $\sp4$He, $\sp3$He, and dilution refrigerators. AuFe alloys in this study have Fe concentrations ranging from 0.1 to 0.4 at%, and their spin glass freezing has been observed in the resistivity $\rho$(T) as a function of temperature, which shows a broad maximum at a temperature T$\rm\sb{m}.$ $\rho$(T) of the AuFe spin glass wires has been investigated for wires of various widths in the range of 150 nm-300 $\mu$m. The resistivity $\rho$(T) of the AuFe wires indeed shows a size dependence. As the width of the wire is reduced, the amplitude of the resistivity maximum increases, and T$\rm\sb{m}$ shifts toward lower temperatures. However, the size dependence originates not from some intrinsic spin glass property, but from the electron-electron interaction contribution to $\rho$(T). The four-terminal differential resistance, dV/dI, has also been measured as a function of dc current bias, I. We find that dV/dI becomes asymmetric in I when the width of at least one voltage terminal is less than 150 nm and different from the width of the other voltage terminal. We analyze dV/dI(I) of the AuFe wires by a model heat flow equation, and find that the asymmetry in dV/dI(I) reflects the size dependence of thermopower in mesoscopic AuFe spin glass wires.
