Photo-induced Hall Effect in Graphene -- Effect of Boundary Types
Takashi Oka, Hideo Aoki
We theoretically predict, with the Keldysh Green's function combined with the Floquet method, that the AC electric field of a circularly polarized light should induce a Hall effect…
Nonequilibrium Steady State of Photoexcited Correlated Electrons in the Presence of Dissipation
Naoto Tsuji, Takashi Oka, Hideo Aoki
We present a framework to determine nonequilibrium steady states in strongly correlated electron systems in the presence of dissipation. This is demonstrated for a correlated elect…
Diagrammatic Monte Carlo simulation of non-equilibrium systems
Philipp Werner, Takashi Oka, Andrew J. Millis
We generalize the recently developed diagrammatic Monte Carlo techniques for quantum impurity models from an imaginary time to a Keldysh formalism suitable for real-time and nonequ…
Photo-induced Tomonaga-Luttinger-like liquid in a Mott insulator
Takashi Oka, Hideo Aoki
Photo-induced metallic states in a Mott insulator are studied for the half-filled, one-dimensional Hubbard model with the time-dependent density matrix renormalization group. An ir…
Correlated electron systems periodically driven out of equilibrium: Floquet + DMFT formalism
Naoto Tsuji, Takashi Oka, Hideo Aoki
We propose to combine the Floquet formalism for systems in ac fields with the dynamical mean-field theory to study correlated electron systems periodically driven out of equilibriu…
Photovoltaic Hall effect in graphene
Takashi Oka, Hideo Aoki
Response of electronic systems in intense lights (AC electric fields) to DC source-drain fields is formulated with the Floquet method. We have then applied the formalism to graphen…
