Exciton-spin interactions in antiferromagnetic charge-transfer insulators
Tatsuya Kaneko, Yuta Murakami, Denis Golež +2
We derive exciton-spin interactions from a microscopic correlated model that captures important aspects of the physics of charge-transfer (CT) insulators to address magnetism assoc…
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…
Interaction quench in the Holstein model: Thermalization crossover from electron- to phonon-dominated relaxation
Yuta Murakami, Philipp Werner, Naoto Tsuji +1
We study the relaxation of the Holstein model after a sudden switch-on of the interaction by means of the nonequilibrium dynamical mean field theory, with the self-consistent Migda…
