Controllable photocurrent generation in Dirac systems with two frequency drives

Yuya Ikeda, Sota Kitamura, Takahiro Morimoto

We study the bulk photovoltaic effect (BPVE) in Dirac and Weyl semimetals under two-frequency light irradiation. We show that the BPVE emerges for centrosymmetric Dirac and Weyl se…
