“…In order to describe multiple brane solutions, the tachyon field needs to be generalized to an N by N tensor field [18]- [22], [14]. The tachyon potential is then [14] V (T ) = Tr(e −T 2 /4 ).…”

In this note, we consider the two derivative truncation of boundary string field theory for the unstable D9 brane in Type IIA string theory. We construct multiples of the stable codimension 1 solitons that correspond to stacks of D8 branes. We find the fluctuation modes that correspond to open strings stretching between the branes, and find that their masses are consistent with the string tension. We show that these modes are localized halfway between the branes and that their width is independent of the brane separation.

The interaction between a parallel brane-antibrane and brane-antibrane is investigated by regarding the brane-antibrane pair as a kink or anti-kink type tachyon condensed state.As the kink-type tachyon condensed state is known as a non-BPS brane we expand the Lagrangian of tachyon effective field theory to the quadratic order in the off-diagonal fluctuation and then use the zeta-function regularization and Schwinger perturbative formula to evaluate the interaction within a kink-kink or a kink-antikink. The results show that while the kink and kink has repulsive force the kink and anti-kink has attractive force and may annihilate by each others. We therefore evaluate the free energy at finite temperature and determine the critical temperature above which the stable state of kink-antikink system may be found.

On non-abelian low energy effective action for D-branes

Abstract: Connection between the partition function for the 2D sigma model with boundary pertubations and the low energy effective action for massless fields in the open string theory is discussed. In the non-abelian case with a stack of N D-branes, the terms up to the order of α ′ 3 are found.
