Super-Tonks-Girardeau quench in the extended Bose-Hubbard model
M Marciniak, M Łebek, J Kopyciński, W Górecki… - Physical Review A, 2023 - APS
We investigate the effect of a quench from a one-dimensional gas with strong and repulsive
local interactions to a strongly attractive one, known as the super-Tonks-Girardeau effect. By …

Universal spin-mixing oscillations in a strongly interacting one-dimensional Fermi gas
We study the spin-mixing dynamics of a one-dimensional strongly repulsive Fermi gas under
harmonic confinement. By employing a mapping onto an inhomogeneous isotropic …

Repulsive dynamics of strongly attractive one-dimensional quantum gases
M Łebek, A Syrwid, PT Grochowski, K Rzążewski - Physical Review A, 2022 - APS
We analyze the dynamics of one-dimensional quantum gases with strongly attractive contact
interactions. We specify a class of initial states for which attractive forces effectively act as …

On the Radial and Angular Correlations in a Confined System of Two Atoms in Two-Dimensional Geometry
P Kościk - arXiv preprint arXiv:2309.14116, 2023 - arxiv.org
We analyzed a system of two bosonic atoms in an isotropic two-dimensional harmonic trap
with a finite-range soft-core interaction model. We carefully examined the correlation …
