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…
Photocurrent induced by a bicircular light drive in centrosymmetric systems
Yuya Ikeda, Sota Kitamura, Takahiro Morimoto
A bicircular light (BCL) consists of left and right circularly polarized lights with different frequencies, and draws a rose-like pattern with a rotational symmetry determined by t…
Floquet engineering of electric polarization with two-frequency drive
Yuya Ikeda, Sota Kitamura, Takahiro Morimoto
Electric polarization is a geometric phenomenon in solids and has a close relationship to the symmetry of the system. Here we propose a mechanism to dynamically induce and manipula…
