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…
