Black holes, black rings, and their microstates

I Bena, NP Warner - Supersymmetric Mechanics-Vol. 3: Attractors and …, 2008 - Springer
In this review article, we describe some of the recent progress towards the construction and
analysis of three-charge configurations in string theory and supergravity. We begin by …

The fuzzball proposal for black holes

K Skenderis, M Taylor - Physics Reports, 2008 - Elsevier
The fuzzball proposal states that associated with a black hole of entropy S, there are
expShorizon-free non-singular solutions that asymptotically look like the black hole but …

Split states, entropy enigmas, holes and halos

F Denef, GW Moore - Journal of High Energy Physics, 2011 - Springer
A bstract We investigate degeneracies of BPS states of D-branes on compact Calabi-Yau
manifolds. We develop a factorization formula for BPS indices using attractor flow trees …

Entanglement between two disjoint universes

V Balasubramanian, A Kar, T Uga** - Journal of High Energy Physics, 2021 - Springer
A bstract We use the replica method to compute the entanglement entropy of a universe
without gravity entangled in a thermofield-double-like state with a disjoint gravitating …

Classification of near-horizon geometries of extremal black holes

HK Kunduri, J Lucietti - Living Reviews in Relativity, 2013 - Springer
Any spacetime containing a degenerate Killing horizon, such as an extremal black hole,
possesses a well-defined notion of a near-horizon geometry. We review such near-horizon …

Bubbling supertubes and foaming black holes

I Bena, NP Warner - Physical Review D—Particles, Fields, Gravitation, and …, 2006 - APS
We construct smooth BPS three-charge geometries that resolve the zero-entropy singularity
of the U (1)× U (1) invariant black ring. This singularity is resolved by a geometric transition …

Black rings

R Emparan, HS Reall - Classical and Quantum Gravity, 2006 - iopscience.iop.org
A black ring is a five-dimensional black hole with an event horizon of topology S 1× S 2. We
provide an introduction to the description of black rings in general relativity and string theory …

Black holes as effective geometries

V Balasubramanian, J De Boer… - … and Quantum Gravity, 2008 - iopscience.iop.org
Gravitational entropy arises in string theory via coarse graining over an underlying space of
microstates. In cases with enough supersymmetry, it has been possible to explicitly construct …

Mergers and typical black hole microstates

I Bena, CW Wang, NP Warner - Journal of High Energy Physics, 2006 - iopscience.iop.org
We use mergers of microstates to obtain the first smooth horizonless microstate solutions
corresponding to a BPS three-charge black hole with a classically large horizon area. These …

Black rings in Taub-NUT space

I Bena, P Kraus, NP Warner - Physical Review D—Particles, Fields, Gravitation …, 2005 - APS
We construct the most generic three-charge, three-dipole-charge, BPS black-ring solutions
in a Taub-NUT background. These solutions depend on seven charges and six moduli, and …
