Kondo Effect and Dephasing in Low-Dimensional Metallic Systems / Edition 1

by Venkat Chandrasekhar, Chris Van Haesendonck, Alfred Zawadowski

Overview

The 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 scatteringof the 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 of the impurities with each other.

Editorial Reviews

The main goal of the May-June workshop was to review theoretical and experimental research on the problem of Kondo-type scattering of the electrons in systems of reduced dimensionalities. Eighteen papers are grouped in sections dealing with finite size effects in Kondo alloys, finite size effects in spin glass alloys, point contact spectroscopy and tunneling spectroscopy of Kondo impurities, two-level systems and dephasing in thin metal structure, and Kondo effect in quantum dots. Also included are 20 poster presentations. Annotation c. Book News, Inc., Portland, OR
