Microstate Geometries from Gauged Supergravity in Three Dimensions
Daniel R. Mayerson, Robert A. Walker, Nicholas P. Warner
The most detailed constructions of microstate geometries, and particularly of superstrata, are done using supergravity coupled to two anti-self-dual tensor mu…
D1-D5-P superstrata in 5 and 6 dimensions: separable wave equations and prepotentials
Robert Walker
We construct the most general single-mode superstrata in 5 dimensions with ambipolar, two centered Gibbons Hawking bases, via dimensional reduction of superstrata in 6 dimensions.…
Early Scrambling and Capped BTZ Geometries
Iosif Bena, Emil J. Martinec, Robert Walker +1
Geodesic probes in certain horizonless microstate geometries experience extreme tidal forces long before reaching the region where these geometries differ significantly from the ex…
The Structure of BPS Equations for Ambi-polar Microstate Geometries
Alexander Tyukov, Robert Walker, Nicholas P. Warner
Ambi-polar metrics, defined so as to allow the signature to change from +4 to -4 across hypersurfaces, are a mainstay in the construction of BPS microstate geometries. This paper e…
