Finite temperature superfluid transition of strongly-correlated lattice bosons in various geometries
T. A. Zaleski, T. K. Kopec
We study finite-temperature properties of the strongly interacting bosons in three-dimensional lattices by employing the combined Bogoliubov method and the quantum rotor approach.…

Temperature-dependent excitation spectra of ultra-cold bosons in optical lattices
T. A. Zaleski, T. K. Kopec
Trapping ultra-cold atoms in optical lattices provides a unique environment for investigating quantum phase transitions between strongly correlated superfluid and Mott insulator ph…
