Abstract

This paper investigates the theoretical hypothesis that light-wave-periodic modulation of electronic hopping between atomic sites occupied by noncollinear local spins can coherently control magnetic states and phase transitions before quasi-stationary states are established. Using quantum kinetic equations for the density matrix of Hubbard quasiparticles, the authors show that time-periodic modulation of electronic hopping can steer an antiferromagnetic insulating state into a metallic state with transient magnetization. This represents an alternative method for controlling magnetic moments in sync with quantum transport.
