Mott transitions in two-orbital Hubbard systems
A. Koga, K. Inaba, N. Kawakami
We investigate the Mott transitions in two-orbital Hubbard systems. Applying the dynamical mean field theory and the self-energy functional approach, we discuss the stability of it…
Phase diagram of orbital-selective Mott transitions at finite temperatures
Kensuke Inaba, Akihisa Koga, Sei-ichiro Suga +1
Mott transitions in the two-orbital Hubbard model with different bandwidths are investigated at finite temperatures. By means of the self-energy functional approach, we discuss the…
Finite-temperature Mott transitions in multi-orbital Hubbard model
Kensuke Inaba, Akihisa Koga, Sei-ichiro Suga +1
We investigate the Mott transitions in the multi-orbital Hubbard model at half-filling by means of the self-energy functional approach. The phase diagrams are obtained at finite te…
