Critical temperature of noninteracting bosonic gases in cubic optical lattices at arbitrary integer fillings
Abdulla Rakhimov, Iman N. Askerzade
We have shown that the critical temperature of a Bose-Einstein condensate to a normal phase transition of noninteracting bosons in cubic optical lattices has a linear dependence on…
Quantum particle in a parabolic lattice in the presence of a gauge field
Andrey R. Kolovsky, Fabian Grusdt, Michael Fleischhauer
We analyze the eigenstates of a two-dimensional lattice with additional harmonic confinement in the presence of an artificial magnetic field. While the softness of the confinement…
Crystallized and amorphous vortices in rotating atomic-molecular Bose-Einstein condensates
Chao-Fei Liu, Heng Fan, Shih-Chuan Gou +1
Vortex is a topological defect with a quantized winding number of the phase in superfluids and superconductors. Here, we investigate the crystallized (triangular, square, honeycomb…
Resonant dynamics of chromium condensates
Tomasz Świsłocki, Jarosław H. Bauer, Mariusz Gajda +1
We numerically study the dynamics of a spinor chromium condensate in low magnetic fields. We show that the condensate evolution has a resonant character revealing rich structure of…
Spin-Orbit Coupled One-Dimensional Fermi Gases with Infinite Repulsion
Xiaoling Cui, Tin-Lun Ho
The current efforts of studying many-body effects with spin-orbit coupling (SOC) using alkali-metal atoms are impeded by the heating effects due to spontaneous emission. Here, we s…
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…
