Staggered ordered phases in the three-orbital Hubbard model
Kosuke Ishigaki, Joji Nasu, Akihisa Koga +2
We study ordered phases with broken translational symmetry in the half-filled three-orbital Hubbard model with antiferromagnetic Hund coupling by means of dynamical mean-field theo…

Symmetry breaking states in the half-filled two-orbital Hubbard model with crystalline electric field
Kosuke Ishigaki, Joji Nasu, Akihisa Koga
We investigate the half-filled two-orbital Hubbard model with the crystalline electric field using dynamical mean-field theory combined with the continuous-time quantum Monte Carlo…

Spontaneously orbital-selective superconductivity in a three-orbital Hubbard model
Kosuke Ishigaki, Joji Nasu, Akihisa Koga +2
We study a three-orbital Hubbard model with negative Hund coupling in infinite dimensions, combining dynamical mean-field theory with continuous time quantum Monte Carlo simulation…
