Complex networks for the description of energy landscapes — •Francesco Rao, Stefanie Muff, and Amedeo Caflisch — Biochemistry Department, University of Zurich, Switzerland

The concept of energy landscapes is of great help for the understanding of dynamical systems. Many applications have emerged for the study of protein folding, clusters and supercooled liquids. Recently, an interesting analogy between complex networks and energy landscapes was shown [1,2]. Here, a method based on weighted network analysis is introduced for the quantitative characterization of free-energy basins. The method is applied in a study of folding for the description of the energy landscape of a 20-residue peptide. Although the method was developed for the analysis of energy landscapes its application can be extended to the study of weighted networks in general.
