Mean-field study of repulsive 2D and 3D Bose polarons

25 Aug 2020 Hryhorchak O. Panochko G. Pastukhov V.

The detailed mean-field treatment of the Bose polaron problem in two and three dimensions is presented. Particularly, assuming that impurity is immersed in the dilute Bose gas and interacts with bosons via the hard-sphere two-body potential, we calculate the low-momentum parameters of its spectrum, namely, the binding energy and the effective mass...
