Entanglement entropy of a simple quantum system
Maurizio Melis
We propose a simple approach to the calculation of the entanglement entropy of a spherically symmetric quantum system composed of two separate regions. We consider bound states of…
Holographic entanglement entropy of the BTZ black hole
M. Cadoni, M. Melis
We investigate quantum entanglement of gravitational configurations in 3D AdS gravity using the AdS/CFT correspondence. We derive explicit formulas for the holographic entanglement…
Microscopic entropy of black holes and AdS_2 quantum gravity
Mariano Cadoni, Maurizio Melis, Paolo Pani
Quantum gravity (QG) on two-dimensional anti-de Sitter spacetime (AdS_2) takes always the form of a chiral conformal field theory (CFT). However, the actual content of the CFT, and…
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…
Global properties of charged dilatonic Gauss-Bonnet black holes
M. Melis, S. Mignemi
We study the phase space of the spherically symmetric solutions of Einstein-Maxwell-Gauss-Bonnet system nonminimally coupled to a scalar field and prove the existence of solutions…
Two-dimensional static black holes with pointlike sources
M. Melis, S. Mignemi
We study the static black hole solutions of generalized two-dimensional dilaton-gravity theories generated by pointlike mass sources, in the hypothesis that the matter is conformal…
