In this article, the renormalized vacuum polarization for a massless, conformally coupled scalar field on asymptotically anti-de Sitter black hole backgrounds is computed.Abstract:
We compute the renormalized vacuum polarization for a massless, conformally coupled scalar field on asymptotically anti--de Sitter black hole backgrounds. Mixed (Robin) boundary conditions are applied on the spacetime boundary. We consider black holes with nonspherical event horizon topology as well as spherical event horizons. The quantum scalar field is in the Hartle-Hawking state, and we employ Euclidean methods to calculate the renormalized expectation values. Far from the black hole, we find that the vacuum polarization approaches a finite limit, which is the same for all boundary conditions except Dirichlet boundary conditions.read more

Black Hole Explosions
TL;DR: In this article, it was shown that any black hole will create and emit particles such as neutrinos or photons at just the rate that one would expect if the black hole was a body with a temperature of (κ/2π) (ħ/2k) ≈ 10−6 (M/M)K where κ is the surface gravity of the body.

Role of boundary conditions on Lifshitz spacetimes
TL;DR: In this article, the authors consider a class of four-dimensional Lifshitz spacetimes with critical exponent $z = 2, including a hyperbolic and a spherical topological black hole, and use mode decomposition to split the equation of motion into a radial and into an angular component.

Vacuum Polarization Instead of “Dark Matter” in a Galaxy
TL;DR: In this paper , the authors considered a vacuum polarization inside a galaxy in the eikonal approximation and found that two possible types of polarization exist, the first being described by the equation of state p=ρ/3, similar to radiation.
