Electrically and magnetically switchable nonlinear photocurrent in РТ-symmetric magnetic topological quantum materials

Abstract Nonlinear photocurrent in time-reversal invariant noncentrosymmetric systems such as ferroelectric semimetals sparked tremendous interest of utilizing nonlinear optics to characterize condensed matter with exotic phases. Here we provide a microscopic theory of two types of second-order nonl...
