TL;DR: In this paper, a quantum entropy function formalism was used to compute logarithmic corrections to the entropy of half BPS black holes in supersymmetric string theories, and these corrections were used to test various proposals for the measure in the OSV formula.

Abstract: Logarithmic corrections to the extremal black hole entropy can be computed purely in terms of the low energy data—the spectrum of massless fields and their interaction. The demand of reproducing these corrections provides a strong constraint on any microscopic theory of quantum gravity that attempts to explain the black hole entropy. Using quantum entropy function formalism we compute logarithmic corrections to the entropy of half BPS black holes in $${{\mathcal N}=2}$$
supersymmetric string theories. Our results allow us to test various proposals for the measure in the OSV formula, and we find agreement with the measure proposed by Denef and Moore if we assume their result to be valid at weak topological string coupling. Our analysis also gives the logarithmic corrections to the entropy of extremal Reissner–Nordstrom black holes in ordinary Einstein–Maxwell theory.

The Black Hole information problem: past, present, and future
TL;DR: A brief overview of the black hole information problem emphasizing fundamental issues and recent proposals for its resolution is given in this paper, where the focus is on broad perspective and providing a guide to current literature rather than presenting full details.
A Universal Counting of Black Hole Microstates in AdS$_4$
TL;DR: In this paper, the authors derived a universal formula which relates the planar limit of the topologically twisted index of these SCFTs and their three-sphere partition function and then utilized this to account for the entropy of a large class of supersymmetric asymptotically AdS$_4$ magnetically charged black holes in M-theory and massive type IIA string theory.

Consistent Supergravity with Complex Spin 3/2 Gauge Fields
TL;DR: In this paper, a new theory of supergravity is constructed which is invariant under complex local supersymmetry transformations, obtained by coupling the massless spin- (3/2,1) multiplet of ordinary global supergravity to the spin- 2,3,2 gauge multiplet.
N=2 extremal black holes.
TL;DR: It is shown that extremal magnetic black hole solutions of N=2 supergravity coupled to vector multiplets with a generic holomorphic prepotential F can be described as supersymmetric solitons which interpolate between maximally symmetric limiting solutions at spatial infinity and the horizon.
Subleading and non-holomorphic corrections to N=2 BPS black hole entropy
TL;DR: In this article, the inverse Laplace transform of a partition function based on a mixed electric/magnetic ensemble is evaluated for black holes with various degrees of supersymmetry and for N = 4 supersymmetric black holes all results agree.
Splitting of an extremal Reissner-Nordström throat via quantum tunneling
TL;DR: The interior near the horizon of an extremal Reissner-Nordstr\"om black hole is taken as an initial state for quantum-mechanical tunneling and an instanton is presented that connects this state with a final state describing the presence of several horizons, interpreted as a WKB description of fluctuations due to a splitting and recombination of the throat into several components.
Arithmetic of quantum entropy function
TL;DR: In this paper, it was shown that the quantum entropy function is insensitive to details of the infrared cutoff used in the computation, and the details of boundary terms added to the action.
