Superfluid-Mott Insulator Transition of Spin-1 Bosons in an Optical Lattice
Shunji Tsuchiya, Susumu Kurihara, Takashi Kimura
We have studied superfluid-Mott insulating transition of spin-1 bosons interacting antiferromagnetically in an optical lattice. We have obtained the zero-temperature phase diagram…

A Variational Sum-Rule Approach to Collective Excitations of a Trapped Bose-Einstein Condensate
Takashi Kimura, Hiroki Saito, Masahito Ueda
It is found that combining an excitation-energy sum rule with Fetter's trial wave function gives almost exact low-lying collective-mode frequencies of a trapped Bose-Einstein conde…
