Vortices under S-duality

Abstract

We investigate a system of 1,3, and 7-branes in type IIB string theory. We identify the 1-brane with the vortex of the Abelian Higgs model. We claim that in the S-dual, the theory on the 3-brane confines electric flux which we identify with the fundamental string and that the dual photon has a mass. We then investigate ways of breaking supersymmetry in the brane set up.
