Impurity self-energy in the strongly-correlated Bose systems
Galyna Panochko, Volodymyr Pastukhov, Ivan Vakarchuk
We proposed the non-perturbative scheme for calculation of the impurity spectrum in the Bose system at zero temperature. The method is based on the path-integral formulation and de…

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…
