Dynamic structure factor of quantum hard rods from exact form-factors
Stanisław Kiedrzyński, Emilia Witkowska, Miłosz Panfil
We study the quantum hard-rods model and obtain compact analytical expressions for density form factors, and a semi-analytical treatment for dynamic and static structure factors ca…
Magnetization-induced reordering of ground states phase diagram in a two-component Bose-Hubbard model
Oskar Stachowiak, Hubert Dunikowski, Emilia Witkowska
We investigate the influence of non-zero magnetization on the ground-state phase diagram of the two-component Bose-Hubbard model. Employing a mean-field theoretical framework, both…
Multisetting protocol for Bell correlated states detection with spin- systems
Arkadiusz Kobus, Xinwei Li, Mariusz Gajda +2
We propose a multisetting protocol for the detection of two-body Bell correlations, and apply it to spin-nematic squeezed states realized in pairs of SU(2) subsystems within sp…
On the fluctuations of the number of atoms in the condensate
Maciej B. Kruk, Piotr Kulik, Malthe F. Andersen +6
Bose-Einstein condensation represents a remarkable phase transition, characterized by the formation of a single quantum subsystem. As a result, the statistical properties of the co…
