Evolution of a single spin in ideal Bose gas at finite temperatures
O. Hryhorchak, G. Panochko, V. Pastukhov
We study the finite-temperature dynamics of non-interacting bosons with a single static spinful impurity immersed. A non-zero contact boson-impurity pairwise interaction is assumed…
Bipolaron in one-dimensional fermions with three-body interaction
O. Hryhorchak, G. Panochko, V. Pastukhov
The properties of the one-dimensional population-imbalanced fermions are discussed. The system is assumed to be in the two-body resonance where all two-body scattering leng…
Static impurities in a weakly-interacting Bose gas
G. Panochko, V. Pastukhov
We present a comprehensive discussion of the ground-state properties of dilute -dimensional Bose gas interacting with a few static impurities. Assuming the short-ranged characte…
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…
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…
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…
