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.

Over ?fteen years ago, because of the tremendous increase in the power and utility of computer simulations, The University of Georgia formed the ?rst institutional unit devoted to the use of simulations in research and teaching: The Center for Simulational Physics. As the international simulations c- munityexpandedfurther, wesensedaneedforameetingplaceforbothex- riencedsimulatorsandneophytestodiscussnewtechniquesandrecentresults in an environment which promoted lively discussion. As a consequence, the Center for Simulational Physics established an annual workshop on Recent DevelopmentsinComputerSimulationStudiesinCondensedMatterPhysics. This year's workshop was the seventeenth in this series, and the continued interest shown by the scienti?c community demonstrates quite clearly the useful purpose that these meetings have served. The latest workshop was held at The University of Georgia, February 16-20, 2004, and these proce- ings 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 o?er a special thanks to IBM and to SGI 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 bene't from specialized results as well as pro't from exposure to new algorithms, methods of analysis, and conceptual dev- opments.

This status report features the most recent developments in the field, spanning a wide range of topical areas in the computer simulation of condensed matter/materials physics. Both established and new topics are included, ranging from the statistical mechanics of classical magnetic spin models to electronic structure calculations, quantum simulations, and simulations of soft condensed matter.
