Vortex splitting and phase separating instabilities of coreless vortices in F=1 spinor Bose-Einstein condensates
M. Takahashi, V. Pietila, M. Mottonen +2
The low lying excitations of coreless vortex states in F = 1 spinor Bose-Einstein condensates (BECs) are theoretically investigated using the Gross-Pitaevskii and Bogoliubov-de Gen…
Non-Abelian magnetic monopole in a Bose-Einstein condensate
Ville Pietilä, Mikko Möttönen
Recently, an effective non-Abelian magnetic field with a topology of a monopole was shown to emerge from the adiabatic motion of multilevel atoms in spatially varying laser fields…
Stability of coreless vortices in ferromagnetic spinor Bose-Einstein condensates
V. Pietila, M. Mottonen, S. M. M. Virtanen
We study the energetic and dynamic stability of coreless vortices in nonrotated spin-1 Bose-Einstein condensates, trapped with a three-dimensional optical potential and a Ioffe-Pri…
Vortex pump for dilute Bose-Einstein condensates
Mikko Mottonen, Ville Pietila, Sami M. M. Virtanen
The formation of vortices by topological phase engineering has been realized experimentally to create the first two- and four-quantum vortices in dilute atomic Bose-Einstein conden…
Stability and dynamics of vortex clusters in nonrotated Bose-Einstein condensates
V. Pietila, M. Mottonen, T. Isoshima +2
We study stationary clusters of vortices and antivortices in dilute pancake-shaped Bose-Einstein condensates confined in nonrotating harmonic traps. Previous theoretical results on…
Splitting times of doubly quantized vortices in dilute Bose-Einstein condensates
J. A. M. Huhtamäki, M. Möttönen, T. Isoshima +2
Recently, the splitting of a topologically created doubly quantized vortex into two singly quantized vortices was experimentally investigated in dilute atomic cigar-shaped Bose-Ein…
