Instability of hyper-compact Kerr-like objects
Vitor Cardoso, Paolo Pani, Mariano Cadoni +1
Viable alternatives to astrophysical black holes include hyper-compact objects without horizon, such as gravastars, boson stars, wormholes and superspinars. The authors have recent…
Microscopic entropy of the charged BTZ black hole
M. Cadoni, M. Melis, M. R. Setare
The charged BTZ black hole is characterized by a power-law curvature singularity generated by the electric charge of the hole. The curvature singularity produces ln r terms in the…
Induced gravity and entanglement entropy of 2D black holes
Mariano Cadoni
Using the fact that 2D Newton constant is wholly induced by a conformal field theory, we derive a formula for the entanglement entropy of the anti-de Sitter black hole in two space…
Ergoregion instability of ultra-compact astrophysical objects
Vitor Cardoso, Paolo Pani, Mariano Cadoni +1
Most of the properties of black holes can be mimicked by horizonless compact objects such as gravastars and boson stars. We show that these ultra-compact objects develop a strong e…
Entanglement entropy of two-dimensional Anti-de Sitter black holes
Mariano Cadoni
Using the AdS/CFT correspondence we derive a formula for the entanglement entropy of the anti-de Sitter black hole in two spacetime dimensions. The leading term in the large black…
A symmetry breaking mechanism for selecting the speed of relativistic solitons
M. Cadoni, R. De Leo, G. Gaeta
We propose a mechanism for fixing the velocity of relativistic soliton based on the breaking of the Lorentz symmetry of the sine-Gordon (SG) model. The proposal is first elaborated…
