Light-induced localized vortices in multicomponent Bose-Einstein condensates
Y. Braver, D. Burba, S. S. Nair +4
We study continuous interaction of a trapped two-component Bose-Einstein condensate with light fields in a -type configuration. Using light beams with orbital angular momentum,…
The Lieb excitations and topological flat mode of spectral function of Tonks-Girardeau gas in Kronig-Penney potential
Wen-Bin He, Giedrius Žlabys, Hoshu Hiyane +2
Lieb excitations are fundamental to the understanding of the low energy behaviour of many-body quantum gases. Here we study the spectral function of a Tonks-Girardeau gas in a fini…
Two-dimensional Thouless pumping in time-space crystalline structures
Y. Braver, C. -h. Fan, G. Žlabys +2
Dynamics of particle in a resonantly driven quantum well can be interpreted as that of a particle in a crystal-like structure, with the time playing the role of the coordinate. By…
One- and two-axis squeezing via laser coupling in an atomic Fermi-Hubbard model
T. Hernández Yanes, M. Płodzień, M. Mackoit Sinkevičienė +3
We study a production of spin-squeezed states with ultra-cold atomic fermions described by the Fermi-Hubbard model in the Mott insulating phase. We show activation of two twisting…
Flow-equation approach to quantum systems driven by an amplitude-modulated time-periodic force
Viktor Novičenko, Giedrius Žlabys, Egidijus Anisimovas
We apply the method of flow equations to describe quantum systems subject to a time-periodic drive with a time-dependent envelope. The driven Hamiltonian is expressed in terms of i…
Spatially strongly confined atomic excitation via two dimensional stimulated Raman adiabatic passage
Hamid R. Hamedi, Giedrius Zlabys, Veronica Ahufinger +3
We consider a method of sub-wavelength superlocalization and patterning of atomic matter waves via a two dimensional stimulated Raman adiabatic passage (2D STIRAP) process. An atom…
