Superstratum Symbiosis.
TL;DR: In this article, superstrata are defined to be the component of the supergraviton gas that is obtained by breaking the CFT into '$|00\rangle$-strands' and acting on each strand with the small, anomaly-free superconformal generators.
Topological stars, black holes and generalized charged Weyl solutions

TL;DR: In this paper, a smooth static bubble solution, denoted as topological stars, was constructed in five-dimensional Einstein-Maxwell theories, which are asymptotic to the number of charged objects.
Smooth Bubbling Geometries Without Supersymmetry
Ibrahima Bah,Pierre Heidmann +1 more
Abstract: We construct the first smooth bubbling geometries using the Weyl formalism. The solutions are obtained from Einstein theory coupled to a two-form gauge field in six dimensions with two compact directions. We classify the charged Weyl solutions in this framework. Smooth solutions consist of a chain of Kaluza-Klein bubbles that can be neutral or wrapped by electromagnetic fluxes, and are free of curvature and conical singularities. We discuss how such topological structures are prevented from gravitational collapse without struts. When embedded in type IIB, the class of solutions describes D1-D5-KKm solutions in the non-BPS regime, and the smooth bubbling solutions have the same conserved charges as a static four-dimensional non-extremal Cvetic-Youm black hole.
