Robin boundary conditions in acoustic BTZ black holes
Christyan C. de Oliveira, Ricardo A. Mosna, João Paulo M. Pitelli
We introduce an analog model for the conformally coupled scalar field on the BTZ black hole. The model is based on the propagation of acoustic waves in a Laval nozzle. Since the BT…
Comment on "Analog Schwarzschild-like geometry in fluids with external pressure''
João Paulo M. Pitelli, Ricardo A. Mosna, Christyan C. de Oliveira +1
In Ref. [1], exact (not only conformally related) analogue models for the Schwarzschild and Reissner-Nordström spacetimes were found. The background non-relativistic fluid flow was…
Analog model for the BTZ black hole
Christyan C. de Oliveira, Ricardo A. Mosna
We present an analog model for the Bañados, Teitelboim, Zanelli (BTZ) black hole based on a hydrodynamical flow. We numerically solve the fully nonlinear hydrodynamic equations of…
Boundary conditions for isolated asymptotically anti-de Sitter spacetimes
Christyan C. de Oliveira, Ricardo A. Mosna, João Paulo M. Pitelli
We revisit the propagation of classical scalar fields in a spacetime which is asymptotically anti-de Sitter. The lack of global hyperbolicity of the underlying background gives ris…
Analogue models for Schwarzschild and Reissner-Nordström spacetimes
Christyan C. de Oliveira, Ricardo A. Mosna, João Paulo M. Pitelli +1
We present analogue models for the Schwarzschild and Reissner-Nordström (RN) spacetimes based on unidirectional hydrodynamic flows. We show that, with appropriate coordinate transf…
