- Abstract: We investigate quantum entanglement in an analogue black hole realized in the
flow of a Bose-Einstein condensate. The system is described by a three-mode
Gaussian state and we construct the corresponding covariance matrix at zero and
finite temperature. We study associated bipartite and tripartite entanglement
measures and discuss their experimental observation. We identify a simple
optical setup equivalent to the analogue Bose-Einstein black hole which
suggests a new way of determining the Hawking temperature and grey-body factor
of the system.
