Light-wave control of correlated materials using quantum magnetism during time-periodic modulation of coherent transport

Abstract

With no direct coupling between spin and light, transient magnetic switching typically proceeds on longer timescales and requires indirect coupling via electric fields. Here, a model based on quantum kinetic equations for the density matrix that characterizes the non-equilibrium quantum state is proposed to describe the response of an antiferromagnetic phase to electron quantum transport during oscillation cycles of a Terahertz electric field.
