Quantum fluctuations on top of a PT-symmetric Bose-Einstein condensate
We investigate the effects of quantum fluctuations citronella horse shampoo in a parity-time (PT) symmetric two-species Bose-Einstein condensate (BEC).It is found that the PT symmetry, though preserved by the macroscopic condensate, can be spontaneously broken by its Bogoliubov quasiparticles under quantum fluctuations.The associated PT-breaking tr
