Non-flat histogram techniques in application to complex free energy landscapes — •Fabio Mueller, Stefan Schnabel, and Wolfhard Janke — Institut für Theoretische Physik, Universität Leipzig, Postfach 100 920, 04009 Leipzig, Germany

Simulation of systems with rugged free-energy landscapes such as spin glasses and polymers are intrinsically difficult and algorithmic improvements for such systems are still needed to enlighten the nature of their low-temperature phase. We developed Monte Carlo non-flat histogram methods, which base on parametric optimization of well-known flat histogram techniques in generalized ensembles, tailored explicitly for systems with complex free-energy landscapes.
