Supercharging Superstrata

Understand

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$_3 \times S^3$ decoupling limit and use the fermionic symmetries of the theory to generate new momentum carrying perturbations in the bulk that have an explicit CFT dual description.
• We then use the supergravity equations to calculate the backreaction of these perturbations and find the full non-linear solutions both in the asymptotically AdS and asymptotically flat case.
• These new geometries have a simpler structure than the previously known superstrata solutions.
