## Spectroscopy of Mott Insulators and Correlated Metals: Proceedings of the 17th Taniguchi Symposium, Kashikojima, Japan, October 24-28, 1994Spectroscopy of Mott Insulators and Correlated Metals Extensive studies of high-Tc cuprate superconductors have stimualted investigations into various transition-metal oxides. Mott transitions in particular provide fascinating problems and new concepts in condensed matter physics. This book is a collection of short overviews by well-known, active researchers in this field. It deals with the latest developments, with particular emphasis on the theoretical, spectroscopic, and transport aspects. |
