Dynamics of large samples of repulsive Fermi gases at nonzero temperatures
Jarosław Ryszkiewicz, Mirosław Brewczyk, Tomasz Karpiuk
We develop a model of a binary fermionic mixture, consisting of large number of atoms, applicable at nonzero temperatures, in the normal phase. We use this approach to study dynami…
Breathing Mode of a Bose-Einstein Condensate Immersed in a Fermi Sea
Piotr T. Grochowski, Tomasz Karpiuk, Mirosław Brewczyk +1
By analyzing breathing mode of a Bose-Einstein condensate repulsively interacting with a polarized fermionic cloud, we further the understanding of a Bose-Fermi mixture recently re…
Nonzero temperature dynamics of a repulsive two-component Fermi gas
Jarosław Ryszkiewicz, Mirosław Brewczyk, Tomasz Karpiuk
We study spin-dipole oscillations of a binary fermionic mixture at nonzero temperatures. We apply the atomic-orbital method combined with the Monte Carlo technique based sampling t…
Collective oscillations of a two-component Fermi gas on the repulsive branch
Tomasz Karpiuk, Piotr T. Grochowski, Mirosław Brewczyk +1
We calculate frequencies of collective oscillations of two-component Fermi gas that is kept on the repulsive branch of its energy spectrum. Not only is a paramagnetic phase explore…
Self-bound Bose-Fermi liquids in lower dimensions
Debraj Rakshit, Tomasz Karpiuk, Paweł Zin +3
We study weakly interacting mixtures of ultracold atoms composed of bosonic and fermionic species in 2D and 1D. When interactions between particles are appropriately tuned, self-bo…
Quantum Bose-Fermi droplets
Debraj Rakshit, Tomasz Karpiuk, Mirosław Brewczyk +1
We study the stability of a zero temperature mixture of attractively interacting degenerate bosons and spin-polarized fermions in the absence of confinement. We demonstrate that hi…
