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…

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…

Behavior of the impurity atom in a weakly-interacting Bose gas
G. Panochko, V. Pastukhov, I. Vakarchuk
We studied the properties of a single impurity atom immersed in a dilute Bose condensate at low temperatures. In particular, we perturbatively obtained the momentum dependence of t…
