Repulsion-to-attraction transition in correlated electron systems triggered by a monocycle pulse
Naoto Tsuji, Takashi Oka, Hideo Aoki +1
We study the time evolution of the Hubbard model driven by a half-cycle or monocycle pulsed electric field F(t) using the nonequilibrium dynamical mean-field theory. We find that f…
Non-linear doublon production in a Mott insulator --- Landau-Dykhne method applied to an integrable model
Takashi Oka
Doublon-hole pair production which takes place during dielectric breakdown in a Mott insulator subject to a strong laser or a static electric field is studied in the one-dimensiona…
Transport properties of non-equilibrium systems under the application of light: Photo-induced quantum Hall insulators without Landau levels
Takuya Kitagawa, Takashi Oka, Arne Brataas +2
In this paper, we study transport properties of non-equilibrium systems under the application of light in many-terminal measurements, using the Floquet picture. We propose and demo…
Strong field physics in condensed matter
Takashi Oka
There are deep similarities between non-linear QFT studied in high-energy and non-equilibrium physics in condensed matter. Ideas such as the Schwinger mechanism and the Volkov stat…
