Interplay between shell structure and trap deformation in dipolar fermi gases
J. Bengtsson, G. Eriksson, J. Josefi +2
Finite fermion systems are known to exhibit shell structure in the weakly-interacting regime, as well known from atoms, nuclei, metallic clusters or even quantum dots in two dimens…
A two-state model for vortex nucleation in a rotating Bose-Einstein condensate
G. Eriksson, J. Bengtsson, G. M. Kavoulakis +1
It is well-known that a rotating Bose-Einstein condensate forms vortices to carry the angular momentum. For a first vortex to nucleate at the trap center, the rotational frequency…
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…
Vortices in fermion droplets with repulsive dipole-dipole interactions
G. Eriksson, J. C. Cremon, M. Manninen +1
Vortices are found in a fermion system with repulsive dipole-dipole interactions, trapped by a rotating quasi-two-dimensional harmonic oscillator potential. Such systems have much…
