Ultrametricity in the externally-induced conformational substates of disordered polymers

  • Ariel Fernández


We investigate the ergodicity breaking in phase space for biopolymers which fold under the influence of an external field. The polymers have random primary sequences and the interactions among monomeric units are of the volume-excluded type. The replica symmetry breaking is shown to have two distinct sources: the two-body interactions between disordered links and the interaction of the random self-avoiding coil with the localized attractive field.
