Hawking effect in BECs acoustic white holes [PDF]
Roberto Balbinot, Alessandro Fabbri, Carlos MayoralBogoliubov pseudoparticle creation in a BEC undergoing a WH like flow is investigated analytically in the case of a one dimensional geometry with stepwise homogeneous regions. Comparison of the results with those corresponding to a BH flow is performed. The implications for the analogous gravitational problem is discussed.View original: http://arxiv.org/abs/1301.2077
