Photo-induced nonequilibrium states in Mott insulators
Yuta Murakami, Denis Golež, Martin Eckstein +1
The study of nonequilibrium phenomena in interacting lattice systems can provide new perspectives on correlation effects, and information on metastable states of matter. Mott insul…
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…
Non-thermal superconductivity in photo-doped multi-orbital Hubbard systems
Sujay Ray, Yuta Murakami, Philipp Werner
Superconductivity in laser-excited correlated electron systems has attracted considerable interest due to reports of light-induced superconducting-like states. Here we explore the…
Majorana Gap Formation in the Anisotropic Kitaev Model with Ordered Flux Configuration
Akihiro Hashimoto, Yuta Murakami, Akihisa Koga
We study the Kitaev model with direction dependent interactions to investigate how the flux configuration and/or the anisotropy in the exchanges affect the Majorana excitations. Sy…
Efficient Control of High Harmonic Generation in Carbon Nanotubes using the Aharonov-Bohm Effect
Yuta Murakami, Kohei Nagai, Akihisa Koga
We show that high-harmonic generation (HHG) in carbon nanotubes (CNTs) can be efficiently controlled using the Aharanov-Bohm (AB) effect. When a static magnetic field (B) is applie…
Dynamical mean-field theory for the Hubbard-Holstein model on a quantum device
Steffen Backes, Yuta Murakami, Shiro Sakai +1
Recent developments in quantum hardware and quantum algorithms have made it possible to utilize the capabilities of current noisy intermediate-scale quantum devices for addressing…
