Finite periodic comb
O. I. Hryhorchak, V. S. Pastukhov
A finit periodic comb was solved by the help of both classical approach based on a direct solving of a Sr\"{odinger} equation and a quantum wave impedance method. It was dem…
Impurity in a three-dimensional unitary Bose gas
O. Hryhorchak, G. Panochko, V. Pastukhov
By using simple and efficient method we discuss properties of a single impurity immersed in three-dimensional Bose gas with the interaction between particles tuned to unitary limit…
Ground-state properties of dilute spinless fermions in fractional dimensions
V. Pastukhov
We analyze zero-temperature universal properties of the simplest Galilean-invariant model of spinless low-dimensional fermions with short-range two-body interactions. In particular…
Mean-field study of repulsive 2D and 3D Bose polarons
O. Hryhorchak, G. Panochko, V. Pastukhov
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…
