Mean-field properties of impurity in Bose gas with three-body forces
Volodymyr Pastukhov
We exactly analyze, on the mean-field level, the low-momentum properties of a single impurity atom loaded in the dilute one-dimensional Bose gas with two- and three-body short-rang…
Ground-state properties of dilute one-dimensional Bose gas with three-body repulsion
Volodymyr Pastukhov
We determined perturbatively the low-energy universal thermodynamics of dilute one-dimensional bosons with the three-body repulsive forces. The final results are presented for the…
Large- properties of a non-ideal Bose gas
Orest Hryhorchak, Volodymyr Pastukhov
We rigorously discuss the large- thermodynamics of a Bose gas with a short-range two-body potential. Considering the system as a mixture of identical components with symmetr…
Ground-state properties of a dilute two-dimensional Bose gas
Volodymyr Pastukhov
We revisit the problem of the calculation of low-temperature properties for the dilute two-dimensional Bose gas. By using Popov's hydrodynamic approach and perturbation theory on t…
Dilute Bose gas in classical environment at low temperatures
Volodymyr Pastukhov
The properties of a dilute Bose gas with the non-Gaussian quenched disorder are analysed. Being more specific we have considered a system of bosons immersed in the classical bath c…
