Predicted DC current induced by propagating wave in gapless Dirac materials
Keisuke Kitayama, Masao Ogata
In this paper, we show that the application of propagating waves can induce a DC current even in systems with spatial inversion symmetry. We derive the equation for the DC current…

Nonlinear optical response in multiband Dirac-Electron System
Keisuke Kitayama, Masao Ogata
We study the dc photocurrent induced by linearly polarized light in a multiband Dirac-electron system, focusing on the organic conductor -(BEDT-TTF)I. Utilizing perturba…
