We review recent progress on the information paradox. We explain why exponentially small
correlations in the radiation emitted by a black hole are sufficient to resolve the original …

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 …

A bstract We describe the experience of an observer falling into a black hole using the
AdS/CFT correspondence. In order to do this, we reconstruct the local bulk operators …

The discussions in § 2 and § 3 make it rather clear that while we have to evaluate a
sequence of functional integrals to compute the Rényi entropies, these are rather complex …

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 …

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 consider string theory on AdS 3× S 3× 𝕋 4 in the tensionless limit, with one unit
of NS-NS flux. This theory is conjectured to describe the symmetric product orbifold CFT. We …

We construct a large family of supergravity solutions that describe BPS excitations on AdS_3
x S^ 3 with angular momentum on S^ 3. These solutions take into account the full …

We construct all 11-dimensional, three-charge BPS solutions that preserve a fixed, standard
set of supersymmetries. Our solutions include all BPS three-charge rotating black holes …

We construct general 2-charge D1-D5 horizon-free non-singular solutions of IIB supergravity
on T 4 and K3 describing fuzzballs with excitations in the internal manifold; these excitations …
