Atom-atom correlations in time-of-flight imaging of ultra-cold bosons in optical lattices
T. A. Zaleski, T. K. Kopeć
We study the spatial correlations of strongly interacting bosons in a ground state, confined in two-dimensional square and three-dimensional cubic lattice. Using combined Bogoliubo…
Finite-temperature effects on the superfluid Bose-Einstein condensation of confined ultracold atoms in three-dimensional optical lattices
T. P. Polak, T. K. Kopeć
We discuss the finite-temperature phase diagram in the three-dimensional Bose-Hubbard (BH) model in the strong correlation regime, relevant for Bose-Einstein condensates in optical…
Frustration effects in rapidly rotating square and triangular optical lattices
T. P. Polak, T. K. Kopeć
We discuss the ground state of the two-dimensional Bose-Hubbard (BH) Hamiltonian, relevant for rotating gaseous Bose-Einstein condensates, by employing \mathrm{U}\left(1\right) qua…
Zero-temperature phase diagram of Bose-Fermi gaseous mixtures in optical lattices
T. P. Polak, T. K. Kopeć
We study the ground state phase diagram of a mixture of bosonic and fermionic cold atoms confined on two- and three-dimensional optical lattices. The coupling between bosonic fluct…
