Entanglement entropy of subtracted geometry black holes (vol 9, 041, 2014)
Mirjam Cvetič, Zain H. Saleem, Alejandro Satz
Polemika, diskusijski prispevek
Oznake: Kvantna logika;Fizika elementarnih delcev;Popravki;
We compute the entanglement entropy of minimally coupled scalar fields on subtracted geometry black hole backgrounds, focusing on the logarithmic corrections. We notice that matching between the entanglement entropy of original black holes and their subtracted counterparts is only at the order of th ...

Gaussian null coordinates for rotating charged black holes and conserved charges
Mirjam Cvetič, Christopher N. Pope, Aritra Saha, Alejandro Satz
Izvirni znanstveni članek
Oznake: supergravitiy;flat spacetime;black hole;four-dimensional rotating;metrics;
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 and five-dimensional extremal rotating black holes in Gaussian null coordinates. We obtain these as expansions in powers ...

Vacuum polarization of STU black holes and their subtracted geometry limit
Mirjam Cvetič, G. W. Gibbons, Zain H. Saleem, Alejandro Satz
Izvirni znanstveni članek
Oznake: black holes;supergravity;string theory;conformal field models;string duality;Kvantna logika;Fizika elementarnih delcev;
We study the vacuum polarization of a massless minimally coupled scalar field at the horizon of four-charge STU black holes. We compare the results for the standard asymptotically flat black holes and for the black holes obtained in the "subtracted limit", both in the general static case and at the ...
