Knots in a spinor Bose-Einstein condensate
Physical review letters, 2008•APS
… We show that knots of spin textures can be created in the polar phase of a spin-1 Bose-Einstein
condensate, and discuss experimental schemes for their generation and probe, together
with their lifetime. … In conclusion, we have shown that a spin-1 polar BoseEinstein
condensate can accommodate a knot, which is also be shown to be created using a
quadrupolar magnetic field. Contrary to knot solitons known in other systems, the knots in
spinor BECs are immune from energetic instability against shrinkage, because the energy …
