Photoinduced dynamics of excitonic order and Rabi oscillation in the two-orbital Hubbard model
Yasuhiro Tanaka, Kenji Yonemitsu
We investigate the condition for the photoinduced enhancement of an excitonic order in a two-orbital Hubbard model, which has been theoretically proposed in our previous work [Phys…
Theory of the Inverse Faraday Effect due to the Rashba Spin-Oribt Interactions: Roles of Band Dispersions and Fermi Surfaces
Yasuhiro Tanaka, Takashi Inoue, Masahito Mochizuki
We theoretically study the inverse Faraday effect, i.e., the optical induction of spin polarization with circularly polarized light, by particularly focusing on effects of band dis…
Photoinduced collective mode, inhomogeneity, and melting in a charge order system
Hitoshi Seo, Yasuhiro Tanaka, Sumio Ishihara
We theoretically investigate photoresponses of a correlated electron system upon stimuli of a pulsed laser light. Real-time dynamics of an interacting spinless fermion model on a o…
Photoinduced enhancement of excitonic order in the two-orbital Hubbard model
Yasuhiro Tanaka, Manabu Daira, Kenji Yonemitsu
Photoinduced dynamics in an excitonic insulator is studied theoretically by using a two-orbital Hubbard model on the square lattice where the excitonic phase in the ground state is…
Correlation Effects on Charge Order and Zero-Gap State in the Organic Conductor α-(BEDT-TTF)2I3
Yasuhiro Tanaka, Masao Ogata
The effects of electron correlation in the quasi-two-dimensional organic conductor α-(BEDT-TTF)2I3 are investigated theoretically by using an extended Hubbard model with on-site an…
Phase Separation Induced by Symmetric Monocycle Optical Pulse in Extended Hubbard Models
Hiroki Yanagiya, Yasuhiro Tanaka, Kenji Yonemitsu
Many-electron dynamics induced by a symmetric monocycle electric-field pulse of large amplitude is theoretically investigated in one- and two-dimensional half-filled extended Hubba…
