Photoinduced pairing in the Kondo lattice model
Tomonori Shirakawa, Shohei Miyakoshi, Seiji Yunoki
The previous theoretical study has shown that pulse irradiation to the Mott insulating state in the Hubbard model can induce the enhancement of superconducting correlation due to t…
Excitonic Insulator State of the Extended Falicov-Kimball Model in the Cluster Dynamical Impurity Approximation
Kosuke Hamada, Tatsuya Kaneko, Shohei Miyakoshi +1
We comparatively study the excitonic insulator state in the extended Falicov-Kimball model (EFKM, a spinless two-band model) on the two-dimensional square lattice using the variati…
Mott Transitions and Staggered Orders in the Three-component Fermionic System: Variational Cluster Approach
Takumi Hasunuma, Tatsuya Kaneko, Shohei Miyakoshi +1
The variational cluster approximation is used to study the ground-state properties and single-particle spectra of the three-component fermionic Hubbard model defined on the two-dim…
