Mean-field phase diagram of disordered bosons in a lattice at non-zero temperature
K. V. Krutitsky, A. Pelster, R. Graham
Bosons in a periodic lattice with on-site disorder at low but non-zero temperature are considered within a mean-field theory. The criteria used for the definition of the superfluid…

First- and second-order superfluid--Mott-insulator phase transitions of spin-1 bosons with coupled ground states in optical lattices
K. V. Krutitsky, M. Timmer, R. Graham
We investigate the superfluid--Mott-insulator quantum phase transition of spin-1 bosons in an optical lattice created by pairs of counterpropagating linearly polarized laser beams,…

Spin-1 bosons with coupled ground states in optical lattices
K. V. Krutitsky, R. Graham
The superfluid--Mott-insulator phase transition of ultracold spin-1 bosons with ferromagnetic and antiferromagnetic interactions in an optical lattice is theoretically investigated…
