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…
Manifestation of relative phase in dynamics of two interacting Bose-Bose droplets
Maciej Pylak, Filip Gampel, Marcin Płodzień +1
We study coherent dynamics of two interacting Bose-Bose droplets by means of the extended Gross-Pitaevskii equation. The relative motion of the droplets couples to the phases of th…
Variational approach for interacting ultra-cold atoms in arbitrary one-dimensional confinement
Przemysław Kościk, Marcin Płodzień, Tomasz Sowiński
Standard analytical construction of the many-body wave function of interacting particles in one dimension, beyond mean-field theory, is based on the Jastrow approach. The many-body…
Few-fermion thermometry
Marcin Płodzień, Rafał Demkowicz-Dobrzański, Tomasz Sowiński
Potential realization of a quantum thermometer operating in the nanokelvin regime, formed by a few-fermionic mixture confined in a one-dimensional harmonic trap, is proposed. Therm…
Numerically exact approach to few-body problems far from a perturbative regime
Marcin Płodzień, Dariusz Wiater, Andrzej Chrostowski +1
Recent developments of experimental techniques in the field of ultra-cold gases open a path to study the crossover from 'few' to 'many' on the quantum level. In this case, accurate…
Synthetic Random Flux Model in a periodically-driven optical lattice
Jan Major, Marcin Płodzień, Omjyoti Dutta +1
We propose a realization of a synthetic Random Flux Model in a two-dimensional optical lattice. Starting from Bose-Hubbard Hamiltonian for two atom species we show how to use fast-…
Rydberg dressing of a one-dimensional Bose-Einstein condensate
Marcin Płodzień, Graham Lochead, Julius de Hond +2
We study the influence of Rydberg dressed interactions in a one-dimensional (1D) Bose-Einstein Condensate (BEC). We show that a 1D geometry offers several advantages over 3D for ob…
Controlling disorder with periodically modulated interactions
Arkadiusz Kosior, Jan Major, Marcin Płodzień +1
We investigate a celebrated problem of one dimensional tight binding model in the presence of disorder leading to Anderson localization from a novel perspective. A binary disorder…
Breakdown of Anderson localization of interacting quantum bright solitons in a disorder potential
Marcin Płodzień, Krzysztof Sacha
The center of mass of a bright soliton in a Bose-Einstein condensate may reveal Anderson localization in the presence of a weak disorder potential. We analyze the effects of intera…
Dark soliton in a disorder potential
Małgorzata Mochol, Marcin Płodzień, Krzysztof Sacha
We consider dark soliton in a Bose-Einstein condensate in the presence of a weak disorder potential. Deformation of the soliton shape is analyzed within the Bogoliubov approach and…
