Physics and Chemistry of Transition-Metal Oxides includes both theoretical and experimental approaches to the variety of phenomena found in the transition-metal oxides, including high-temperature superconductivity, colossal magnetoresistance, and metal-insulator transition. These are the central issues in materials science and condensed matter physics/chemistry, and readers can obtain up-to-date information on what is happening in this field of research.

This book contains the invited review papers and contributed papers presented at the University of Tokyo International Symposium on Anderson localization. It provides an overview of rapidly developing topics related to this area, including the metal-insulator transition in doped semiconductors and disordered metals, weak localization phenomena in two- and three-dimensional dirty metals and semiconductor space-charge layers, the quantum Hall effect, and localization in strong magnetic fields, together with the newer subjects of quasicrystals and mesoscopic systems. Quasicrystals are particularly interesting because their wave functions exhibit self-similarity and are marginally localized or delocalized, while in mesoscopic systems the conductance is no longer a self-averaged quantity and fluctuations play an essential role. This volume should be of use to anyone interested in the development of Anderson localization.

This volume contains the proceedings of the ffiM Japan International Sympo­ sium on Strong Correlation and Superconductivity, which was held in Keidan­ ren Guest House at the foot of Mt. Fuji, May 21-25, 1989. The purpose of the Symposium was to provide an opportunity for discus­ sions on the problem of strong correlation of electrons in the context of high-Tc superconductivity. Sixty-eight scientists were invited from seven countries and forty-three papers were presented in the Symposium. Soon after the discovery ofhigh-Tc superconducting oxides, Professor P. W. Anderson proposed that the essence of high-Tc superconductivity lies in the strong correlation among the electrons in these materials. This proposal has stimulated a wide range of theoretical investigations on this profound and dif­ ficult problem, which are expected to lead eventually to new concepts describ­ ing strong electron correlation. In the Symposium, Anderson himself started lively discussions by his talk entitled "Myth and Reality in High-Tc Supercon­ ductivity", which was followed by various reports on theoretical studies and experimental results. Concise and thoughtful summaries of experiment and theory were given by Professors H. R. Ott and P. A. Lee, respectively. It is our hope that this volume reflects the present status of the research activity on this outstanding problem from the viewpoint of the basic physics and that it will further stimulate the effort to understand these fascinating systems, the high-Tc oxides.
