Energy flow during relaxation in an electron-phonon system with multiple modes: A nonequilibrium Green's function study
Ken Inayoshi, Akihisa Koga, Yuta Murakami
We investigate an energy flow in an extended Holstein model describing electron systems coupled to hot-phonons and heat-bath phonons. To analyze the relaxation process after the ph…
Photoinduced Phase Transition in Two-Band model on Penrose Tiling
Ken Inayoshi, Yuta Murakami, Akihisa Koga
We study the effects of the photo irradiation on the band insulating state in the two-band Hubbard model on the Penrose tiling. Examining the time- and site-dependent physical quan…
Photo-induced Dynamics of Quasicrystalline Excitonic Insulator
Ken Inayoshi, Yuta Murakami, Akihisa Koga
We study the photo-induced dynamics of the excitonic insulator in the two-band Hubbard model on the Penrose tiling by means of the time-dependent real-space mean-field approximatio…
Excitonic condensation reflecting electronic states in two-band Penrose-Hubbard model
Ken Inayoshi, Yuta Murakami, Akihisa Koga
We study the excitonic insulating (EI) phase in the two-band Hubbard models on the Penrose tiling. Performing the real-space mean-field calculations systematically, we obtain the g…
