Superstrata

Understand

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 some of the microstates of the D1-D5-P black hole in string theory.
• They are the most general microstate geometries of that sort whose CFT dual states are identified.
• After reviewing relevant features of the dual CFT, we discuss the construction of superstratum solutions in supergravity, based on the linear structure of the BPS equations.
