Persistent and enhanced spin-nematic squeezing in a spinor Bose-Einstein condensate
文献摘要：
We propose a simple scheme to realize the persistent spin-nematic squeezing in a spinor Bose-Einstein condensate by rapidly turning-off the external magnetic field at a time that maximal spin-nematic squeezing occurs.We observe that the optimal spin-nematic squeezing can be maintained in a nearly fixed direction.For a proper initial magnetic field,the optimal squeezing can be obviously enhanced.We further construct a spin-mixing interferometer,where the quantum correlation of the squeezed state(generated by our scheme)is fully utilized in the phase measurement,and show the phase sensitivity of the interferometer has a significant enhancement.
