Piazza, F.Sanejouand, Y.-H.2010-03-162010-03-162010-03-16200910.1209/0295-5075/88/68001https://infoscience.epfl.ch/handle/20.500.14299/48145WOS:000273854100030We investigate how nonlinearity and topological disorder affect the energy relaxation of local kicks in coarse-grained network models of proteins. We find that nonlinearity promotes long-range, coherent transfer of substantial energy to specific functional sites, while depressing transfer to generic locations. In some cases, transfer is mediated by the self-localization of discrete breathers at distant locations from the kick, acting as efficient energy-accumulating centers.
