Reentrant transition of bosons in a quasiperiodic potential

, 2010
We investigate the behavior of a two dimensional array of Bose-Einstein condensate tubes described by means of a Bose-Hubbard Hamiltonian. Using a Wannier function expansion for the wavefunction in each tube, we compute the Bose-Hubbard parameters ...

Number-conserving master equation theory for a dilute Bose-Einstein condensate

, 2010
We describe the transition of $N$ weakly interacting atoms into a Bose-Einstein condensate within a number-conserving quantum master equation theory. Based on the separation of time scales for condensate formation and non-condensate thermalization, we ...

Phase Transitions in Ultra-Cold Two-Dimensional Bose Gases

, 2006
We briefly review the theory of Bose-Einstein condensation in the two-dimensional trapped Bose gas and, in particular the relationship to the theory of the homogeneous two-dimensional gas and the Berezinskii-Kosterlitz-Thouless phase.

Enhancement and suppression of spontaneous emission and light scattering by quantum degeneracy

, 2000
Quantum degeneracy modifies light scattering and spontaneous emission. For fermions, Pauli blocking leads to a suppression of both processes. In contrast, in a weakly interacting Bose-Einstein condensate, we find spontaneous emission to be enhanced ...

Probing the hollowing transition of a shell-shaped Bose-Einstein condensate with collective excitation

Physical Review Research
We investigate the hollowing transition of a shell-shaped Bose-Einstein condensate using collective excitations. The shell is created using an immiscible dual-species Bose-Einstein condensate mixture, with its hollowness controlled by tuning the ...

Rotating binary Bose-Einstein condensates and vortex clusters in quantum droplets

, 2019
Quantum droplets may form out of a gaseous Bose-Einstein condensate, stabilized by quantum fluctuations beyond mean field. We show that multiple singly-quantized vortices may form in these droplets at moderate angular momenta in two dimensions.
