Massive quantum divergence on the Cauchy horizon of a black hole
Marc Casals, Lorenzo Pisani, Peter Taylor
We investigate a quantum massive scalar field in the interior of a charged and spherically-symmetric (Reissner-Nordström) black hole. We examine the behaviour for varying values of…
Vacuum polarization and renormalized stress-energy tensor of spherical thin shells
Julio Arrechea, Cormac Breen, Adrian Ottewill +2
We provide a thorough study of the properties of the Boulware vacuum in the spacetime of a spherical, static thin shell with a Minkowski interior. To this end, we calculate the ren…
Maximum Entropy Least Squares Solutions of Overdetermined Linear Systems
Felice Iavernaro, Monica Lazzo, Lorenzo Pisani
We investigate the theoretical foundations of a recently introduced entropy-based formulation of weighted least squares for the approximation of overdetermined linear systems, moti…
The renormalized stress-energy tensor for scalar fields in the Boulware state with applications to extremal black holes
Julio Arrechea, Cormac Breen, Adrian Ottewill +2
We provide a mode-sum prescription to directly compute the renormalized stress-energy tensor (RSET) for scalar fields in the Boulware vacuum. The method generalizes the recently de…
Klein-Gordon-Maxwell Systems with Nonconstant Coupling Coefficient
Monica Lazzo, Lorenzo Pisani
We study a Klein-Gordon-Maxwell system, in a bounded spatial domain, under Neumann boundary conditions on the electric potential. We allow a nonconstant coupling coefficient. For s…
Mathematical aspects relative to the fluid statics of a self-gravitating perfect-gas isothermal sphere
Pierluigi Amodio, Domenico Giordano, Felice Iavernaro +4
In the present paper we analyze and discuss some mathematical aspects of the fluid-static configurations of a self-gravitating perfect gas enclosed in a spherical solid shell. The…
