Density-Wave and Antiferromagnetic States of Fermionic Atoms in Optical Lattices
Takuji Higashiyama, Kensuke Inaba, Sei-ichiro Suga
We study the two-band effects on ultracold fermionic atoms in optical lattices by means of dynamical mean-field theory. We find that at half-filling the atomic-density-wave (ADW) s…
Supersolid state in fermionic optical lattice systems
Akihisa Koga, Takuji Higashiyama, Kensuke Inaba +2
We study ultracold fermionic atoms trapped in an optical lattice with harmonic confinement by combining the real-space dynamical mean-field theory with a two-site impurity solver.…
Multiband-Driven Superfluid-Insulator Transition of Fermionic Atoms in Optical Lattices: A Dynamical Mean-Field-Theory Study
Takuji Higashiyama, Kensuke Inaba, Sei-ichiro Suga
The superfluid-insulator transitions of the fermionic atoms in optical lattices are investigated by the two-site dynamical mean-field theory. It is shown that the Mott transition o…
Supersolid state of ultracold fermions in an optical lattice
Akihisa Koga, Takuji Higashiyama, Kensuke Inaba +2
We study ultracold fermionic atoms trapped in an optical lattice with harmonic confinement by means of the dynamical mean-field approximation. It is demonstrated that a supersolid…
