Creation of a Dirac monopole-antimonopole pair in a spin-1 Bose-Einstein condensate
Konstantin Tiurev, Pekko Kuopanportti, Mikko Möttönen
We theoretically demonstrate that a pair of Dirac monopoles with opposite synthetic charges can be created within a single spin-1 Bose-Einstein condensate by steering the spin degr…
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…
Evolution of an isolated monopole in a spin-1 Bose-Einstein condensate
Konstantin Tiurev, Pekko Kuopanportti, András Márton Gunyhó +2
We simulate the decay dynamics of an isolated monopole defect in the nematic vector of a spin-1 Bose-Einstein condensate during the polar-to-ferromagnetic phase transition of the s…
Tying Quantum Knots
David S. Hall, Michael W. Ray, Konstantin Tiurev +3
Knots are familiar entities that appear at a captivating nexus of art, technology, mathematics, and science. As topologically stable objects within field theories, they have been s…
Decay of an isolated monopole into a Dirac monopole configuration
K. Tiurev, E. Ruokokoski, H. Mäkelä +2
We study numerically the detailed structure and decay dynamics of isolated monopoles in conditions similar to those of their recent experimental discovery. We find that the core of…
