This proceedings volume contains selected talks and poster presentations from the 9th International Conference on Path Integrals — New Trends and Perspectives, which took place at the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany, during the period September 23-28, 2007. Continuing the well-developed tradition of the conference series, the present status of both the different techniques of path integral calculations and their diverse applications to many fields of physics and chemistry is reviewed. This is reflected in the main topics in this volume, which...

This volume on spin glasses, structural glasses and biological macromolecules collects pedagogically written lecture notes of internationally renowned - perts from eight countries, who work on di?erent physical problems but - ploy similar theoretical concepts and computational methods. The research into at ?rst sight quite di?erent physical phenomena, therefore, faces related problems, whose origin can be traced back to the di?culties of numerical simulations of systems with rugged free-energy landscapes. Many of the or- inal publications presuppose quite specialized common knowledge, usually...
