WebWe study the back-reaction associated with Hawking evaporation of an acoustic canonical analogue black hole in a Bose–Einstein condensate. We show that the emission of Hawking radiation induces a local back-reaction on the condensate, perturbing it in the near-horizon region, and a global back-reaction in the density distribution of the atoms. We … WebMar 25, 2024 · The Schwarzschild metric takes on its simplest form in Schwarzschild coordinates. It has the least number of non-zero components. This makes it particularly easy to work with.
