We propose an analogy between the quantum physics of a black hole in its late stages of the evaporation process and a superfluid Bose-Einstein condensate (BEC), based on the Horowitz and Maldacena quantum final-state projection model [J. High Energy Phys. 02 (2004), 008JHEPFG1029-847910.1088/1126-6708/2004/02/008]. The superfluid region is considered to be analogous to the interior of a black hole, and the normal fluid/superfluid interface is compared to the event horizon of a black hole. We theoretically investigate the possibility of recovering the wave function of particles incident on a superfluid BEC from the normal fluid, facilitated by the mode conversion processes occurring at the normal fluid/superfluid BEC interface. We also study how the correlations of an infalling mode with an external memory system can be preserved in the process, similar to Hayden and Preskill’s “information mirror” model for a black hole [J. High Energy Phys. 09 (2007), 120JHEPFG1029-847910.1088/1126-6708/2007/09/120]. Based on these analogies, we conjecture that the quantum state of bosons entering a black hole in its final state is the superfluid quantum ground state of interacting bosons. Our analogy suggests that the wave function of bosons falling into a black hole can be recovered from the outgoing Hawking modes. In the particular case in which a holelike quasiparticle (a density dip) is incident on the superfluid BEC causing the superfluid to shrink in size, our model indicates that the evaporation is unitary.
