Searching for cosmic vortices
Marek NikoÅajuk, Tomasz Karpiuk, MirosÅaw Brewczyk
Our study focuses on the strong tidal disruption of a cold helium white dwarf passing a black hole. We model the white dwarf as a Bose-Fermi droplet and use quantum hydrodynamic eq…
Three-dimensional Bose-Fermi droplets at nonzero temperatures
Maciej Lewkowicz, MirosÅaw Brewczyk, Mariusz Gajda +1
Using numerical methods, we study the formation of self-bound quantum Bose-Fermi droplets at nonzero temperatures. We describe an attractive atomic Bose-Fermi mixture using quantum…
Dynamic formation of supersolid phase in a mixture of ultracold bosonic and fermionic atoms
Maciej Lewkowicz, Tomasz Karpiuk, Mariusz Gajda +1
We numerically study the dynamical properties of a mixture consisting of a dipolar condensate and a degenerate Fermi gas in a quasi-one-dimensional geometry. In particular, we focu…
Competitive algorithms for calculating the ground state properties of Bose-Fermi mixtures
Tomasz ÅwisÅocki, Krzysztof Gawryluk, MirosÅaw Brewczyk +1
In this work we define, analyze, and compare different numerical schemes that can be used to study the ground state properties of Bose-Fermi systems, such as mixtures of different…
Studying the radiation of a white dwarf star falling onto a black hole
Marek NikoÅajuk, Tomasz Karpiuk, Lorenzo Ducci +1
We investigate electromagnetic and gravitational radiation generated during the process of the tidal stripping of a white dwarf star circulating a black hole. We go beyond Chandras…
Supersolidity of dipolar Bose-Einstein condensates induced by coupling to fermions
Maciej Lewkowicz, Tomasz Karpiuk, Mariusz Gajda +1
We study a mixture of a repulsive dipolar condensate and a degenerate Fermi gas in a quasi-one-dimensional geometry. We demonstrate that the presence of fermions, which attract bos…
