Correlation evolution in dilute Bose-Einstein condensates after quantum quenches
Joanna Pietraszewicz, Magdalena Stobińska, Piotr Deuar
The universal forms of quantum density and phase correlations after an interaction quench are found for dilute 1d, 2d, and 3d condensates. A Bogoliubov approach in a local density…
Tunneling-Induced Restoration of the Degeneracy and the Time-Reversal Symmetry Breaking in Optical Lattices
Tomasz Sowiński, Mateusz Łacki, Omjyoti Dutta +5
We study the ground-state properties of bosons loaded into the -band of a one dimensional optical lattice. We show that the phase diagram of the system is substantially affected…
Spin dynamics of two bosons in an optical lattice site: a role of anharmonicity and anisotropy of the trapping potential
Joanna Pietraszewicz, Tomasz Sowiński, Mirosław Brewczyk +2
We study a spin dynamics of two magnetic Chromium atoms trapped in a single site of a deep optical lattice in a resonant magnetic field. Dipole-dipole interactions couple spin degr…
