Effects of collective modes on nonlinear conductivity

ORAL

Abstract

Nonlinear conductivity can provide insight into the symmetry properties of materials. Previous work shows that in a correlated insulator with time reversal symmetry, order parameter fluctuations can generate an injection current under light irradiation. We give a more detailed analysis of this result.
