Dirac Electrons in AC-Magnetic Fields: -Landau Levels and Chiral Anomaly-Induced Homodyne Effect
Sota Kitamura, Takashi Oka
Floquet engineering, which involves controlling systems through time-periodic driving, is a method for coherently manipulating quantum materials and realizing dynamical states with…

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…

Unexpected linear conductivity in Landau-Zener model: limitations and improvements of the relaxation time approximation in the quantum master equation
Ibuki Terada, Sota Kitamura, Hiroshi Watanabe +1
The nonequilibrium steady states of quantum materials have many challenges. Here, we highlight issues with the relaxation time approximation (RTA) for the DC conductivity in insula…
