Three-dimensional skyrmions in spin-2 Bose-Einstein condensates
K. Tiurev, T. Ollikainen, P. Kuopanportti +3
We introduce topologically stable three-dimensional skyrmions in the cyclic and biaxial nematic phases of a spin-2 Bose-Einstein condensate. These skyrmions exhibit exceptionally h…

Quantum knots in Bose-Einstein condensates created by counterdiabatic control
T. Ollikainen, S. Masuda, M. Möttönen +1
We theoretically study the creation of knot structures in the polar phase of spin-1 BECs using the counterdiabatic protocol in an unusual fashion. We provide an analytic solution t…
