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 ...

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 ...

External magnetic fields can probe the composite structure of black holes in string theory. With this motivation we study magnetised four-charge black holes in the STU model, a consistent truncation of maximally supersymmetric supergravity with four types of electromagnetic fields. We employ solutio ...
