Quantum dynamics of spinful impurity in ideal Bose gas
O. Hryhorchak, V. Pastukhov
We discuss the quench dynamics of an isolated system composed of a single spinful impurity in the transverse Rabi field and bath of non-interacting three- and two-dimensional boson…
Two- and three-body bound states in one-dimensional Fermi bipolaron with three-body interaction
O. Hryhorchak, V. Pastukhov
We discuss the ground-state properties of two bosonic (or spin-1/2 fermionic in a singlet spin state) impurities immersed in a one-dimensional ideal Fermi gas with only the three-b…
Four-body physics in low-dimensional bosons with three-body interaction
V. Polkanov, O. Hryhorchak, V. Pastukhov
The two-channel model for bosons with the three-body interaction is proposed. Similar to the Hamiltonian describing narrow Feshbach resonance in the two-body sector, our model incl…
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…
Strongly interacting Bose-Fermi mixtures in dimensions
V. Pastukhov
Thermodynamically stable low-temperature phases of the Bose-Fermi mixtures composed of bosons and spinless fermions close to four dimensions are considered. In the regime, where th…
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…
