Gaussian null coordinates, near-horizon geometry and conserved charges on the horizon of extremal non-dilatonic black -branes

Mirjam Cvetič, Paulo J. Porfírio, Alejandro Satz

In this paper, we examine the emergence of conserved charges on the horizon of a particular class of extremal non-dilatonic black -branes (which reduce to extremal dilatonic bla…

Gaussian Null Coordinates for Rotating Charged Black Holes and Conserved Charges

M. Cvetic, C. N. Pope, A. Saha +1

Motivated by the study of conserved Aretakis charges for a scalar field on the horizon of an extremal black hole, we construct the metrics for certain classes of four-dimensional a…

Entropy of a subalgebra of observables and the geometric entanglement entropy

Eugenio Bianchi, Alejandro Satz

The geometric entanglement entropy of a quantum field in the vacuum state is known to be divergent and, when regularized, to scale as the area of the boundary of the region. Here w…

General relation between Aretakis charge and Newman-Penrose charge

Mirjam Cvetic, Alejandro Satz

We reexamine the relation between the Aretakis charge of an extremal black hole spacetime and the Newman-Penrose charge of a weakly asymptotically flat spacetime obtained from the…

Vacuum polarization throughout general subtracted black hole spacetimes

Alejandro Satz, Mirjam Cvetic

We compute the vacuum polarization of a massless minimally co pled scalar field in a background given by a black hole with subtracted geometry. Extending previous results for the h…

An analytical formula for the vacuum polarization of rotating black holes

Mirjam Cvetic, Zain H. Saleem, Alejandro Satz

We give an analytical formula for the vacuum polarization of a massless minimally coupled scalar field at the horizon of a rotating black hole with subtracted geometry. This is the…
