Interaction-driven losses for atoms in a dark-state lattice
Piotr Kubala, Mateusz Łącki
In this work we estimate the collisional loss rate of ultracold bosons in the optical potential featuring subwavelength-width peaks. This is established by using arrangement of…

-band stability of ultracold atom gas in anharmonic optical lattice potential with large energy scales
Mateusz Łącki
Using an optical potential with subwavelength resolution in the form of sharp -like peaks, new potential landscapes are created with increased anharmonicity in placement of latt…

Extended Bose-Hubbard Model with dipolar and contact interactions
Krzysztof Biedroń, Mateusz Łącki, Jakub Zakrzewski
We study the phase diagram of the one-dimensional boson gas trapped inside an optical lattice with contact and dipolar interaction taking into account next-nearest terms for both t…
