We show that the boundary state description of a Dp-brane is strictly related to the corresponding classical solution of the low-energy string effective action. By projecting the boundary state on the massless states of the closed string we obtain the tension, the R-R charge and the large-distance behavior of the classical solution. We discuss both the case of a single D-brane and that of bound states of two D-branes. We also show that in the R-R sector the boundary state, written in a picture… Expand
(F,Dp) bound states from the boundary state
Abstract We use the boundary state formalism to provide the full conformal description of (F,D p ) bound states. These are BPS configurations that arise from a superposition of a fundamental stringExpand

Stable non-BPS D-branes in type I string theory
Abstract We use the boundary state formalism to study, from the closed string point of view, superpositions of branes and anti-branes which are relevant in some non-perturbative string dualities.Expand
The geometry of fractional branes

Closed string radiation from moving D-branes
We compute the amplitude for the radiation of massless NS-NS closed string states from the interaction of two moving D-branes. We consider particle-like D-branes with reference to four-dimensionalExpand
D-branes in type 0 string theory
Abstract Using boundary states we derive the presence of (chiral) fermions on the intersection of type 0 D-branes. The corresponding anomalous couplings on the branes are then computed. Furthermore,Expand
Non-commutative open string and D-brane
Abstract In this paper we consider the quantization of open strings ending on D-branes with a background B field. We find that space-time coordinates of the open string end-points becomeExpand
