Multi-Superthreads and Supersheets
Benjamin E. Niehoff, Orestis Vasilakis, Nicholas P. Warner · 2016
We obtain new BPS solutions of six-dimensional, N = 1 supergravity coupled to a ten-sor multiplet. These solutions are sourced by multiple “superthreads ” carrying D1-D5-P charges and two magnetic dipole charges. These new solutions are sourced by multiple threads with independent and arbitrary shapes and include new shape-shape interaction terms. Because the individual superthreads can be given independent profiles, the new solutions can be smeared together into continuous “supersheets, ” described by arbitrary functions of two variables. The supersheet solutions have singularities like those of the three-charge, two dipole-charge generalized supertube in five dimensions and we show how such five-dimensional solutions emerge from a very simple choice of profiles. The new so-lutions obtained here also represent an important step in finding superstrata, which are expected to play a role in the description of black-hole microstates, due to their ability to store a large amount of entropy in their two-dimensional profile. ar X iv
