Tachyon Condensation on Torus and T-duality
arXiv:0806.0975 · doi:10.1088/1126-6708/2008/10/033
Abstract
We find an exact solution, with a nonzero net D-brane charge, in the boundary string field theory of brane-anti-brane pairs on a torus. We explicitly take the T-dual of this configuration. The Nahm-transformation of the instantons is derived from the tachyon condensation.
