Weakly nonlinear dynamics in anti-de Sitter (AdS) spacetimes is reviewed, kee** an eye
on the AdS instability conjecture and focusing on the resonant approximation that accurately …

A bstract We construct a three-parameter family of non-extremal microstate geometries, or
“microstrata”, that are dual to states and deformations of the D1-D5 CFT. These families are …

Cosmological acceleration is difficult to accommodate in theories of fundamental
interactions involving supergravity and superstrings. An alternative is that the acceleration is …

A bstract We construct a cohomogeneity-1 helical black string in six-dimensional Einstein
gravity. The helical solution branches from the onset of the gravitational superradiant …

Press and Teukolsky famously introduced the concept of a black hole bomb system: a scalar
field scattering a Kerr black hole confined inside a mirror undergoes superradiant …

Some interesting recent advances in the theoretical understanding of neural networks have
been informed by results from the physics of disordered many-body systems. Motivated by …

We construct dynamical black hole solutions with a helical symmetry in AdS 5, called black
resonators, as well as their horizonless limits, called geons. We introduce a cohomogeneity …

A bstract Black resonators and geons in global AdS are rapidly rotating, low-energy
solutions with a helical Killing field. We study the linear mode stability of equal angular …

A bstract We study rotating global AdS solutions in five-dimensional Einstein gravity coupled
to a multiplet complex scalar within a cohomogeneity-1 ansatz. The onset of the gravitational …

A bstract We study periodically driven scalar fields and the resulting geometries with global
AdS asymptotics. These solutions describe the strongly coupled dynamics of dual finite-size …
