Elementary excitations of antiferromagnetic spin-1 bosons in an optical lattice
Misako Shinozaki, Shunji Tsuchiya, Shumpei Abe +2
We study elementary excitations of spin-1 bosons with antiferromagnetic interaction in an optical lattice by applying the Gutzwiller approximation to the spin-1 Bose-Hubbard model.…

First-order phase transition and anomalous hysteresis of Bose gases in optical lattices
Daisuke Yamamoto, Takeshi Ozaki, Carlos A. R. Sá de Melo +1
We study the first-order quantum phase transitions of Bose gases in optical lattices. A special emphasis is placed on an anomalous hysteresis behavior, in which the phase transitio…
