Neil Lambert Kings College BPS D-branes are a central part of modern string theory. In particular they lie at the heart of many duality conjectures, including the AdS/CFT correspondence. As is well known their low energy dynamics is governed by a supersymmetric guage theory. In this talk we will discuss so-called non-BPS branes and their low energy dynamics, which are described by a non-supersymmetric gauge theory. We also discuss the one-loop quantum corrections and their physical interpretation in terms of brane dynamics.
