Topological Origin of the Phase Transition in a Model of DNA Denaturation
arXiv:cond-mat/0309665 · doi:10.1103/PhysRevLett.92.158102
Abstract
The hypothesis that phase transitions originate from some topological change of the critical level hypersurface of the potential energy receives direct evident support by our study of the Bishop--Peyrard model of DNA thermal denaturation.
