Asymptotically flat (1,m,n) superstrata: a farewell to AdS

Willem Govaerts, Robert Walker

Superstrata microstate geometries furnish some of the most successful laboratories, to date, for probing black hole microstructure in a geometric setting. This paper extends the (1…

Separability in Consistent Truncations

Krzysztof Pilch, Robert Walker, Nicholas P. Warner

The separability of the Hamilton-Jacobi equation has a well-known connection to the existence of Killing vectors and rank-two Killing tensors. This paper combines this connection w…

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…

Holomorphic Waves of Black Hole Microstructure

Pierre Heidmann, Daniel R. Mayerson, Robert Walker +1

We obtain the largest families constructed to date of -BPS solutions of type IIB supergravity. They have the same charges and mass as supersymmetric D1-D5-P black hol…

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…
