Theory of nonequilibrium pump/probe electronic Raman scattering in strongly correlated materials

ORAL

Abstract

We employ nonequilibrium dynamical mean-field theory to solve for the nonresonant B1g response of a strongly correlated material after a large electric field pump. This electronic Raman scattering channel has no vertex corrections even in nonequilibrium. The problem can be exactly solved for the Falicov-Kimball model at half-filling, which exhibits a Mott metal-insulator transition. We describe what the response looks like for these nonequilibrium systems and show what features emerge due to the nonequilibrium nature of the experiment. Similar calculations can also be done for the A1g response, but they require vertex corrections.
