Backreaction equations for 1+1 dimensional BEC sonic black holes
arXiv:2509.09403 · doi:10.1103/9m8k-ml6s
Abstract
As in the gravitational context, one of the most challenging open question in analogue black holes formed in Bose-Einstein condensates concerns the backreaction of Hawking-like radiation on the condensate and its subsequent evolution. In this work we derive the basic equations describing this backreaction within the density-phase formalism, which avoids infrared divergences and is particularly well suited to one-dimensional configurations.
