The scattering process of a sound-wave perturbation impimping on a rotating acoustic black-hole is numerically investigated using the mathematical tools recently developed in numerical relativity for rotating Kerr black holes. Preliminary results indicate that modern methods from numerical relativity can be successfully adapted to the numerical investigation of analogies between gravitational black holes and condensed matter phenomena.

Abstract
The scattering process of a sound-wave perturbation impimping on a rotating acoustic black-hole is numerically investigated using the mathematical tools recently developed in numerical relativity for rotating Kerr black holes. Preliminary results indicate that modern methods from numerical relativity can be successfully adapted to the numerical investigation of analogies between gravitational black holes and condensed matter phenomena. However, subtle effects, such as stimulated emission from the black-hole ergo-sphere (super-radiance), require very careful and well resolved simulations.File in questo prodotto:
