Superfluid-Mott Insulator Transition of Spin-2 Cold Bosons in an Optical Lattice in a Magnetic Field
Shuo Jin, Jing-Min Hou, Bing-Hao Xie +2
The superfluid-Mott insulator transition of spin-2 boson atoms with repulsive interaction in an optical lattice in a magnetic field is presented. By using the mean field theory, Mo…

Quantum Phase Transition of Spin-2 Cold Bosons in an Optical Lattice
Jing-Min Hou, Mo-Lin Ge
The Bose-Hubbard Hamiltonian of spin-2 cold bosons with repulsive interaction in an optical lattice is proposed. After neglecting the hopping term, the site-independent Hamiltonian…
