Angular-resolved nonlinear optical response as a probe of Lorentz violation in noncentrosymmetric materials

Guilherme J. Inacio, Nathanael N. Batista, Wesley Spalenza +3

We propose a methodology to detect weak Lorentz-violating (LV) backgrounds through the nonlinear shift photocurrent in noncentrosymmetric crystals. Using a spinful Rice--Mele model…
