Imprinting knots in a spinor Bose-Einstein condensate via a Raman process without knotted optical fields
We propose a dynamical imprinting scheme to create nodal lines of torus and lemniscate knots via a Raman process in a dilute spinor Bose-Einstein condensate.We calculate the desired parameters and the necessary spatial profiles of the Raman Push Button Switch laser fields that couple a realistic multilevel atomic system, and demonstrate the imprint
