Logarithmic corrections to extremal black hole entropy from quantum entropy function
TL;DR: In this paper, the quantum entropy function formalism was used to calculate logarithmic corrections to the entropy of black holes in the near horizon geometry of N = 4 supergravity.
Journal ArticleDOI
Logarithmic Corrections to N=4 and N=8 Black Hole Entropy: A One Loop Test of Quantum Gravity
TL;DR: In this paper, the entropy of supersymmetric extremal black holes in N = 4 and N = 8 supersymmymmetric string theories was investigated and the one-loop determinant of massless fields around the near horizon geometry was evaluated.
Journal ArticleDOI
Logarithmic corrections to $$ \mathcal{N} = {4} $$ and $$ \mathcal{N} = {8} $$ black hole entropy: a one loop test of quantum gravity
TL;DR: In this article, the entropy of supersymmetric extremal black holes has been analyzed in terms of the one-loop determinant of massless fields around the near horizon geometry, including contributions from dynamical four dimensional gravitons propagating in the loop.
Journal ArticleDOI
The heat kernel on AdS
TL;DR: In this paper, the authors explicitly evaluate the heat kernel for the Laplacian of arbitrary spin tensor fields on the thermal quotient of (Euclidean) AdS N ≥ 3 using the group theoretic techniques employed for AdS 3 in arXiv:0911.5085.
Journal ArticleDOI
Stability, tunneling and flux changing de Sitter transitions in the large volume string scenario
S.P. de Alwis,S.P. de Alwis,Rajesh Kumar Gupta,Ehsan Hatefi,Fernando Quevedo,Fernando Quevedo +5 more
TL;DR: In this paper, the authors studied the nonperturbative stability of the Large Volume Scenario (LVS) of IIB string compactifications, by analysing transitions mediated by the Brown-Teitelboim (BT) brane nucleations and by Coleman De Luccia tunneling (CDL).
