Two- and three-body effective potentials between impurities in ideal BEC
G. Panochko, V. Pastukhov
We exactly calculate the full temperature dependence of Casimir-like forces appearing between two and three static impurities loaded in the ideal Bose gas below the Bose-Einstein c…
Large- expansion for condensation and stability of Bose-Bose mixtures at finite temperatures
Orest Hryhorchak, Volodymyr Pastukhov
The two-component mixture of Bose particles with short-range pairwise interaction at finite temperatures in three dimensions is considered. Particularly we examine, by means of the…
Mean-field construction for spectrum of one-dimensional Bose polaron
Galyna Panochko, Volodymyr Pastukhov
The full momentum dependence of spectrum of a point-like impurity immersed in a dilute one-dimensional Bose gas is calculated on the mean-field level. In particular we elaborate, t…
Anomalous frequency shifts in a one-dimensional trapped Bose gas
Manuel Valiente, Volodymyr Pastukhov
We consider a system of interacting bosons in one dimension at a two-body resonance. This system, which is weakly interacting, is known to give rise to effective three-particle int…
Condensation and superfluidity of Bose gas
Orest Hryhorchak, Volodymyr Pastukhov
We perform the comprehensive comparison of properties of the condensate and superfluid densities for the -component three-dimensional Bose gas with the symmetric inter- and intr…
