# Habemus superstratum! A constructive proof of the existence of superstrata

@article{Bena2015HabemusSA, title={Habemus superstratum! A constructive proof of the existence of superstrata}, author={Iosif Bena and Stefano Giusto and Rodolfo Russo and Masaki Shigemori and Nicholas P. Warner}, journal={Journal of High Energy Physics}, year={2015}, volume={2015}, pages={1-55} }

A bstractWe construct the first example of a superstratum: a class of smooth horizonless supergravity solutions that are parameterized by arbitrary continuous functions of (at least) two variables and have the same charges as the supersymmetric D1-D5-P black hole. We work in Type IIB string theory on T4 or K3 and our solutions involve a subset of fields that can be described by a six-dimensional supergravity with two tensor multiplets. The solutions can thus be constructed using a linear…
