We investigate the effects of quantum fluctuations 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. https://ashleyshomestores.shop/product-category/7-piece-outdoor-modular-seating/
