Stationary States of Trapped Spin-Orbit-Coupled Bose-Einstein Condensates
Emmi Ruokokoski, Jukka A. M. Huhtamäki, Mikko Möttönen
We numerically investigate low-energy stationary states of pseudospin-1 Bose-Einstein condensates in the presence of Rashba-Dresselhaus-type spin-orbit coupling. We show that for e…
Size and dynamics of vortex dipoles in dilute Bose-Einstein condensates
Pekko Kuopanportti, Jukka A. M. Huhtamäki, Mikko Möttönen
Recently, Freilich et al. [Science 329, 1182 (2010)] experimentally discovered stationary states of vortex dipoles, pairs of vortices of opposite circulation, in dilute Bose-Einste…
Spin textures in condensates with large dipole moments
J. A. M. Huhtamäki, M. Takahashi, T. P. Simula +2
We have solved numerically the ground states of a Bose-Einstein condensate in the presence of dipolar interparticle forces using a semiclassical approach. Our motivation is to mode…
Textures and non-Abelian vortices in atomic d-wave paired Fermi condensates
H. M. Adachi, Y. Tsutsumi, J. A. M. Huhtamäki +1
We report on fundamental properties of superfluids with d-wave pairing symmetry. We consider neutral atomic Fermi gases in a harmonic trap, the pairing being produced by a Feshbach…
Dynamically stable multiply quantized vortices in dilute Bose-Einstein condensates
J. A. M. Huhtamäki, M. Möttönen, S. M. M. Virtanen
Multiquantum vortices in dilute atomic Bose-Einstein condensates confined in long cigar-shaped traps are known to be both energetically and dynamically unstable. They tend to split…
Instabilities of off-centered vortices in a Bose-Einstein condensate
Tomoya Isoshima, Jukka Huhtamäki, Martti M. Salomaa
We study numerically the excitations of off-centered vortices in a Bose-Einstein condensate. The displacement of a single vortex and the separation of a doubly quantized vortex are…
