Variational approach to the ground state of an impurity in Bose-Einstein condensate
Alexey Novikov, Mikhail Ovchinnikov
In this paper we consider the effect of self-localization of a quantum impurity in Bose-Einstein condensate. Space correlation function of the impurity is evaluated with the help o…

Diagrammatic calculation of energy spectrum of quantum impurity in degenerate Bose-Einstein condensate
Alexey Novikov, Mikhail Ovchinnikov
In this paper we considered a quantum particle moving through delute Bose-Einstein condensate at zero temperature. In our formulation the impurity particle interacts with the gas o…

Motion of quantum particle in dilute Bose-Einstein condensate at zero temperature
Alexey Novikov, Mikhail Ovchinnikov
The motion of single quantum particle through Bose-Einstein condensate (BEC) is considered within perturbation theory with respect to the particle-BEC interaction. The Hamiltonian…
