We investigate the backreaction equations for an acoustic black hole formed in a Laval nozzle under the assumption that the motion of the fluid is one-dimensional. The solution in the near-horizon region shows that as phonons are (thermally) radiated the sonic horizon shrinks and the temperature decreases. This contrasts with the behaviour of Schwarzschild black holes, and is similar to what happens in the evaporation of (near-extremal) Reissner-Nordstrom black holes (i.e. infinite evaporation time). Finally, by appropriate boundary conditions the solution is extended in both the asymptotic regions of the nozzle.

  1. Analog model for Euclidean wormholes: Bose-Einstein condensate with dirty surfaces

    gr-qc 2024-12 reject novelty 4.0 of 10

    Random surface fields in a Bose-Einstein condensate are claimed to generate non-local effective interactions that mimic Euclidean wormholes, with a disorder-induced Casimir pressure as the leading consequence.
