Finite-temperature quantum rotor approach for ultracold bosons in optical lattices
M. Rodríguez Martín, T. A. Zaleski
Interacting bosons in optical lattices directly expose quantum phases in a clean, highly controllable environment. This requires engineering systems with very low entropies, but th…
Superexchange Interaction in Insulating EuZnP
Karan Singh, Shovan Dan, A. Ptok +4
We report magnetic and transport properties of single-crystalline EuZnP, which has trigonal CaAlSi-type crystal structure and orders antiferromagnetically at $\…
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…
Time-of-flight patterns of ultra-cold bosons in optical lattices in various Abelian artificial magnetic field gauges
T. P. Polak, T. A. Zaleski
We calculate the time-of-flight patterns of strongly interacting bosons confined in two-dimensional square lattice in the presence of an artificial magnetic field using quantum rot…
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…
