An Elementary Mode Coupling Theory of Random Heteropolymer Dynamics

Abstract

The Langevin dynamics of a random heteropolymer and its dynamic glass transition are studied using elementary mode coupling theory. Contrary to recent reports using a similar framework, a discontinuous ergodic-nonergodic phase transition is predicted for all Rouse modes at a finite temperature T_A. For sufficiently long chains, T_A is almost independent of chain length and is in good agreement with the value previously estimated by a static replica theory.
