Q-Balls Meet Fuzzballs: Non-BPS Microstate Geometries
Bogdan Ganchev, Anthony Houppe, Nicholas Warner
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 non-ext…

Supersymmetry and Superstrata in Three Dimensions
Anthony Houppe, Nicholas P. Warner
We analyze the supersymmetry transformations of gauged supergravity coupled to extra hypermultiplets in three dimensions, and find large families of smooth BPS solutions th…

Delaying the Inevitable: Tidal Disruption in Microstate Geometries
Iosif Bena, Anthony Houppe, Nicholas P. Warner
Microstate geometries in string theory replace the black-hole horizon with a smooth geometric "cap" at the horizon scale. In geometries constructed using superstratum technology, t…
