Phase separation of a repulsive two-component Fermi gas at the two- to three-dimensional crossover
Piotr T. Grochowski, Martin-Isbjörn Trappe, Tomasz Karpiuk +1
We present a theoretical analysis of phase separations between two repulsively interacting components in an ultracold fermionic gas, occurring at the dimensional crossover in a har…
Repulsive dynamics of strongly attractive one-dimensional quantum gases
Maciej Łebek, Andrzej Syrwid, Piotr T. Grochowski +1
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…
Phase Transitions of Repulsive Two-Component Fermi Gases in Two Dimensions
Martin-Isbjörn Trappe, Piotr T. Grochowski, Jun Hao Hue +2
We predict the phase separations of two-dimensional Fermi gases with repulsive contact-type interactions between two spin components. Using density-potential functional theory with…
Many-body molecule formation at a domain wall in a one-dimensional strongly interacting ultracold Fermi gas
Andrzej Syrwid, Maciej Łebek, Piotr T. Grochowski +1
We analyze how the presence of the bound state on top of strong intercomponent contact repulsion affects the dynamics of a two-component ultracold Fermi gas confined in a one-dimen…
Single- to many-body crossover of a quantum carpet
Maciej Łebek, Piotr T. Grochowski, Kazimierz Rzążewski
Strongly interacting many-body system of bosons exhibiting the quantum carpet pattern is investigated exactly by using Gaudin solutions. We show that this highly coherent design us…
Breakdown of the mean field for dark solitons of dipolar bosons in a one-dimensional harmonic trap
Michał Kowalski, Rafał Ołdziejewski, Kazimierz Rzążewski
We directly compare the mean-field and the many-body approach in a one-dimensional Bose system in a harmonic trap. Both contact and dipolar interactions are considered. We propose…
