First-order superfluid-Mott insulator transition of spinor bosons in an optical lattice
Takashi Kimura, Shunji Tsuchiya, Susumu Kurihara
We study the superfluid-Mott insulator transition of antiferromagnetic spin-1 bosons in an optical lattice described by a Bose-Hubbard model. Our variational study with the Gutzwil…

Effects of fermion-boson interaction in neutral atomic systems
Nobuhiko Yokoshi, Susumu Kurihara
We investigate the collective excitations of He-He mixture films at zero temperature within random phase approximation and linear response theory. In low concentration regi…

Analytical treatment of interacting Fermi gas in arbitrary dimensional harmonic trap
Hiroyuki Yoshimoto, Susumu Kurihara
We study normal state properties of an interacting Fermi gas in an isotropic harmonic trap of arbitrary dimensions. We exactly calculate the first-order perturbation terms in the g…
