Microcanonical Analysis of Polymer Aggregation — •Christoph Junghans, Michael Bachmann, and Wolfhard Janke — Institut für Theoretische Physik, Universität Leipzig

We propose the use of microcanonical analyses for heteropolymer aggregation transitions [1,2]. Performing multicanonical Monte Carlo simulations of a simple hydrophobic-polar continuum model for interacting heteropolymers of finite length, we find a first-order-like behavior in the transition region between the phases of fragmented and aggregated configurations.
