Fluctuating hydrodynamics for a chain of nonlinearly coupled rotators

Abstract

We study chains of rotators from the perspective of nonlinear fluctuating hydrodynamics. As confirmed by previous MD simulations, at intermediate temperatures diffusive transport is predicted. At low temperatures we obtain the FPU scenario with suppressed heat peak.
