Computer Simulation Studies in Condensed-Matter Physics XV

Over fifteen years ago, because of the tremendous increase in the power and utility of computer simulations, The University of Georgia formed the first institutional unit devoted to the use of simulations in research and teach ing: The Center for Simulational Physics. As the international simulations community expanded further, we sensed a need for a meeting place for both experienced simulators and neophytes to discuss new techniques and recent results in an environment which promoted lively discussion. As a consequence, the Center for Simulational Physics established an annual workshop on Re cent Developments in Computer Simulation Studies in Condensed Matter Physics. This year's workshop was the fifteenth in this series, and the con tinued interest shown by the scientific community demonstrates quite clearly the useful purpose that these meetings have served. The latest workshop was held at The University of Georgia, March 11-15, 2002, and these proceedings provide a "status report" on a number of important topics. This volume is published with the goal of timely dissemination of the material to a wider audience. We wish to offer a special thanks to IBM Corporation and to the National Science Foundation for partial support of this year's workshop. This volume contains both invited papers and contributed presentations on problems in both classical and quantum condensed matter physics. We hope that each reader will benefit from specialized results as well as profit from exposure to new algorithms, methods of analysis, and conceptual devel opments. Athens, GA, USA D. P.

Status report on the latest developments in simulations in condensed-matter physics

Autorentext
David P. Landau is the Distinguished Professor of Physics and Director of the Center for Simulational Physics at the University of Georgia.

Klappentext
This book is a status report. It provides a broad overview of the most recent developments in the field, spanning a wide range of topical areas in simulational condensed matter physics. These areas include recent developments in simulations of classical statistical mechanics models, electronic structure calculations, quantum simulations, and simulations of polymers. Both new physical results and novel simulational and data analysis methods are presented. Some of the highlights of this volume include detailed accounts of recent theoretical developments in electronic structure calculations, novel quantum simulation techniques and their applications to strongly interacting lattice fermion models, and a wide variety of applications of existing methods as well as novel methods in the simulation of classical statistical mechanics models, including spin glasses and polymers.
