Spin texture and spin current in excitonic phases of the two-band Hubbard model
Hisao Nishida, Shohei Miyakoshi, Tatsuya Kaneko +2
Using the mean-field approximation, we study the -space spin textures and local spin currents emerged in the spin-triplet excitonic insulator states of the two-band Hubbard mode…
Photoinduced Pairing in the Hubbard Model
Tatsuya Kaneko, Tomonori Shirakawa, Sandro Sorella +1
By employing unbiased numerical methods, we show that pulse irradiation can induce unconventional superconductivity even in the Mott insulator of the Hubbard model. The superconduc…
Strong Coupling Nature of the Excitonic Insulator State in TaNiSe
K. Sugimoto, S. Nishimoto, T. Kaneko +1
We analyze the measured optical conductivity spectra using the density-functional-theory-based electronic structure calculation and density-matrix renormalization group calculation…
