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…

Competition of superfluid phases in low-dimensional spin- fermions with - and -wave interactions
A. Nikolaeva, O. Hryhorchak, V. Pastukhov
The ground state of spin- fermions with contact -wave inter- and -wave intra-species interactions is discussed. Particularly, we formulate the mean field scheme for…

Trapped ideal Bose gas with a few heavy impurities
O. Hryhorchak, V. Pastukhov
We formulate a general scheme for calculation of thermodynamic properties of ideal Bose gas with microscopic number of static impurities immersed, when the system is loaded in the…
