Parallel flat-histogram method for equilibrium and non-equilibrium problems

ORAL · Invited

Abstract

I will present a parallel implementation of the multicanonical method and its generalization to a flat-histogram method suitable for other equilibrium ensembles as well as non-equilibrium problems. After a tutorial introduction to the method, I will present several successful applications to diverse equilibrium problems, both on- and off-lattice, and new applications to spreading processes.
