Computer Simulation Studies in Condensed Matter Physics III: Proceedings of the Third Workshop Athens, Ga, Usa, February 12-16, 1990

This book provides a broad overview of recent developments in computer simulation studies of condensed matter systÄms. The contributions present new physical results, simulation techniques, and ways of interpreting simulational data. Topics include: - simulations of disorder and diffusion in metallic alloys; - simulations of viscous flows, polymer dynamics and nucleation; - histogram techniques; - cellular automata; - simulations of phase transitions in systems of molec- ules with internal degrees of freedom; - variational and path-integral Monte Carlo studies of Hubbard models and high-temperature supercon- ductivity; - analytic continuation of imaginary-time Monte Carlo data; - Monte Carlo studies of two-dimensional quantum antiferromagnets at low temperatures.

The contribution of computer simulation studies to our understanding of the prop- erties of a wide range of condensed matter systems is now weIl established. The Center for Simulational Physics of the University of Georgia has been hosting a series of annual workshops with the intent of bringing together experienced prac- titioners in the field, as weIl as relative newcomers, to provide a forum for the exchange of ideas and recent results. This year's workshop, the third in the series, was held February 12-16, 1990. These proceedings are arecord of the workshop and are published with the goal of timely dissemination of the papers to a wider audience. The proceedings are divided into four parts. The first contains invited pa- pers dealing with simulational studies of classical systems and also includes an introduction to some new simulation techniques. Aseparate section is devoted to invited papers on quantum systems, including new results for strongly correlated electron and quantum spin models believed to be important for the description of high-Tc superconductors. The third part consists of a single invited paper, which presents a comprehensive treatment of issues associated with high perfor- mance computing, including differences in architectures and a discussion of access strategies. The contributed papers constitute the final part.

These proBeedings provide researchers and students with an excellent overview of the most important recent progress in computer simulation studies in condensed matter physics. Simulations of disorder phenomena and Monte Carlo techniques are particularly emphasized.
