Exact solution for Bloch oscillations of a simple charge-density-wave insulator

Abstract

Charge-density-wave systems have a static modulation of the electronic charge at low temperatures when they enter an ordered state. While they have been studied for decades in equilibrium, it is only recently that they have been examined in nonequilibrium with time-resolved studies. Here, we present the exact solution for the nonequilibrium response of electrons (in the simplest model for a charge density wave) when the system is placed under a strong DC electric field. This allows us to examine the formation of driven Bloch oscillations and how the presence of a current modifies the nonequilibrium density of states.
