WebGreenwood formula, we obtain the leading correction to the conventional intrinsic SHC in the uniform electric field. We show that such a leading term, which is the square term of the electric field wave vector, depends on band velocity as well as gauge-invariant geometric quan-tities: quantum metric and interband Berry connection. omegacheck tm lowWebDUFTY ET AL. 151 by the ion average.
