# Fuzzballs with internal excitations

@article{Kanitscheider2007FuzzballsWI, title={Fuzzballs with internal excitations}, author={Ingmar Kanitscheider and Kostas Skenderis and Marika Taylor}, journal={Journal of High Energy Physics}, year={2007}, volume={2007}, pages={056-056} }

We construct general 2-charge D1-D5 horizon-free non-singular solutions of IIB supergravity on T4 and K3 describing fuzzballs with excitations in the internal manifold; these excitations are characterized by arbitrary curves. The solutions are obtained via dualities from F1-P solutions of heterotic and type IIB on T4 for the K3 and T4 cases, respectively. We compute the holographic data encoded in these solutions, and show that the internal excitations are captured by vevs of chiral primaries…

- 2018

In all cases, the correlators of two heavy and two light operators in the strong coupling and large c limit of the D1D5 CFT find that they have the properties expected for correlators among pure states in a unitary theory, in particular they do not decay at large Lorentzian times.
