A new class of semiclassical gravity solutions, gravitational quantum stealths and regular Cauchy horizons
Benito A. Juárez-Aubry
We consider semiclassical gravity with a Klein-Gordon field with mass and curvature coupling . We identify a special class of Hadamard two-point functions for…
Renormalisation in maximally symmetric spaces and semiclassical gravity in Anti-de Sitter spacetime
Benito A. Juárez-Aubry, Milton C. Mamani-Leqque
We obtain semiclassical gravity solutions in the Poincaré fundamental domain of -dimensional Anti-de Sitter spacetime, PAdS, with a (massive or massless) Klein-Gordon f…
Quantum strong cosmic censorship and black hole evaporation
Benito A. Juárez-Aubry
It is common folklore that semiclassical arguments suggest that in black hole evaporation an initially pure state can become mixed. This is known as the \emph{information loss puzz…
The Hadamard condition on a Cauchy surface and the renormalized stress-energy tensor
Benito A. Juárez-Aubry, Bernard S. Kay, Tonatiuh Miramontes +1
Given a Cauchy surface in a curved spacetime and a suitably defined quantum state on the CCR algebra of the Klein-Gordon quantum field on that surface, we show, by expanding the sq…
