Computer Simulation Studies in Condensed-Matter Physics XII: Proceedings of the Twelfth Workshop, Athens, G.A., U.S.A., March 8-12, 1999

This volume is a status report based on the presentations and discussions that took place during the 12th Annual Workshop on Computer Simulation Studies in Condensed Matter Physics at the Center for Simulation Physics at the University of Georgia in March 1999. 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 Monte Carlo simulations and simulations of polymers. New physical results and novel simulation and data analysis methods are presented.

As the 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 extended discussion. As a consequence, the Center for Sim­ ulational Physics established an annual workshop on Recent Developments in Computer Simulation Studies in Condensed Matter Physics. This year's workshop was the twelfth in this series. It was held at The University of Geor­ gia, March 8-12, 1999 as an unofficial satellite conference to the Centennial Meeting of the American Physical Society in Atlanta, GA. The continued interest shown by the scientific community demonstrates quite clearly the useful purpose which the series has served. These proceedings provide a "sta­ tus 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 special thanks to IBM Corporation for their generous 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. This volume is a status report based on presentations made at an annual workshop on computer simulation studies in condensed matter physics. It provides a broad overview of developments in the field, spanning a wide range of topical areas in simulational condensed matter physics.
