Pairing in a system of a few attractive fermions in a harmonic trap
Tomasz Sowiński, Mariusz Gajda, Kazimierz Rzążewski
We study a strongly attractive system of a few spin-1/2 fermions confined in a one-dimensional harmonic trap, interacting via two-body contact potential. Performing exact diagonali…
Non-standard Hubbard models in optical lattices: a review
Omjyoti Dutta, Mariusz Gajda, Philipp Hauke +5
Originally, the Hubbard model has been derived for describing the behaviour of strongly-correlated electrons in solids. However, since over a decade now, variations of it are also…
Optimization as a route towards observing the Einstein-de Haas effect in a rubidium condensate
Tomasz Świsłocki, Mariusz Gajda, Mirosław Brewczyk
The main obstacle in experimental realization of the Einstein-de Haas effect in a Bose-Einstein condensate is necessity of a very precise control of the extremely small (of the ord…
Correspondence between dark solitons and the type II excitations of Lieb-Liniger model
T. Karpiuk, T. Sowinski, M. Gajda +2
A one-dimensional model of bosons with repulsive short-range interactions, solved analytically by Lieb and Liniger many years ago, predicts existence of two branches of elementary…
