Rotating binary Bose-Einstein condensates and vortex clusters in quantum droplets
M. Nilsson Tengstrand, P. Stürmer, E. Karabulut +1
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…
Finite-size effects in the dynamics of few bosons in a ring potential
G. Eriksson, J. Bengtsson, E. Ö. Karabulut +2
We study the temporal evolution of a small number of ultra-cold bosonic atoms confined in a ring potential. Assuming that initially the system is in a solitary-wave solution of…
Spin-orbit-coupled Bose-Einstein-condensed atoms confined in annular potentials
E. Ö. Karabulut, F. Malet, A. L. Fetter +2
A spin-orbit-coupled Bose-Einstein-condensed cloud of atoms confined in an annular trapping potential shows a variety of phases that we investigate in the present study. Starting w…
Density functional theory for strongly-correlated bosonic and fermionic ultracold dipolar and ionic gases
F. Malet, A. Mirtschink, C. B. Mendl +4
We introduce a density functional formalism to study the ground-state properties of strongly-correlated dipolar and ionic ultracold bosonic and fermionic gases, based on the self-c…
Rotating Bose-Einstein condensates: Closing the gap between exact and mean-field solutions
J. C. Cremon, A. D. Jackson, E. \" O. Karabulut +3
When a Bose-Einstein condensed cloud of atoms is given some angular momentum, it forms vortices arranged in structures with a discrete rotational symmetry. For these vortex states,…
Wigner-localized states in spin-orbit-coupled bosonic ultracold atoms with dipolar interaction
Y. Yousefi, E. Ö. Karabulut, F. Malet +2
We investigate the occurence of Wigner-localization phenomena in bosonic dipolar ultracold few-body systems with Rashba-like spin-orbit coupling. We show that the latter strongly e…
Phase diagram of a rapidly-rotating two-component Bose gas
E. Ö. Karabulut, F. Malet, G. M. Kavoulakis +1
We derive analytically the phase diagram of a two-component Bose gas confined in an anharmonic potential, which becomes exact and universal in the limit of weak interactions and sm…
Rotational properties of non-dipolar and dipolar Bose-Einstein condensates confined in annular potentials
E. Ö. Karabulut, F. Malet, G. M. Kavoulakis +1
We investigate the rotational response of both non-dipolar and dipolar Bose-Einstein condensates confined in an annular potential. For the non-dipolar case we identify certain crit…
