Gutzwiller study of spin-1 bosons in an optical lattice under a magnetic field
Takashi Kimura, Shunji Tsuchiya, Makoto Yamashita +1
We study spin-1 bosons in an optical lattice under a magnetic field by the Gutzwiller approximation. Our results thus obtained join the discontinuous phase boundary curves obtained…

Maximal entanglement of two spinor Bose-Einstein condensates
Michael W. Jack, Makoto Yamashita
Starting with two weakly-coupled anti-ferromagnetic spinor condensates, we show that by changing the sign of the coefficient of the spin interaction, , via an optically-indu…

Bose-Hubbard model with attractive interactions
Michael W. Jack, Makoto Yamashita
We consider the Bose-Hubbard model of atoms in an optical lattice potential when the atom-atom interactions are attractive. If the lowest energy lattice sites are degenerate (such…
