We give a survey of the present status of the microstate geometries called superstrata.
Superstrata are smooth, horizonless solutions of six-dimensional supergravity that represent …

The black-hole information paradox provides one of the sharpest foci for the conflict between
quantum mechanics and general relativity and has become the proving-ground of would-be …

We construct the first family of horizonless supergravity solutions that have the same mass,
charges, and angular momenta as general supersymmetric rotating D 1-D 5-P black holes in …

A bstract We construct the first example of a superstratum: a class of smooth horizonless
supergravity solutions that are parameterized by arbitrary continuous functions of (at least) …

A bstract We construct an infinite family of smooth asymptotically-flat supergravity solutions
that have the same charges and angular momenta as general supersymmetric D1-D5-P …

A bstract Given an asymptotically Anti-de Sitter supergravity solution, one can obtain a
microscopic interpretation by identifying the corresponding state in the holographically dual …

A bstract We obtain the largest families constructed to date of\(\frac {1}{8}\)-BPS solutions of
type IIB supergravity. They have the same charges and mass as supersymmetric D1-D5-P …

A bstract We construct a new class of smooth horizonless microstate geometries of the
supersymmetric D1-D5-P black hole in type IIB supergravity. We first work in the AdS 3× S 3 …

A bstract We find a two-parameter family of generalized superstrata that emerge as smooth,
supersymmetric solutions in three-dimensional gauged supergravity coupled to additional …

A bstract We comment on a recent paper of Almheiri, Marolf, Polchinski and Sully who argue
against black hole complementarity based on the claim that an infalling observer 'burns' as …
