Noncommutative Tachyon Kinks as D(p− 1)-branes from Unstable Dp-brane
We study noncommutative (NC) field theory of a real NC tachyon and NC U(1) gauge field, describing the dynamics of an unstable Dp-brane. For every given set of diagonal component of open string metric G0, NC parameter θ0, and interpolating electric field Ê, we find all possible static NC kinks as exact solutions, in spite of complicated NC terms, which are classified by an array of NC kink-anti...
متن کاملGeometrical Tachyon Kinks and NS 5 Branes
We further investigate the NS5 ring background using the tachyon map. Mapping the radion fields to the rolling tachyon helps to explain the motion of a probe Dp-brane in this background. It turns out that the radion field becomes tachyonic when the brane is confined to one dimensional motion inside the ring. We find explicit solutions for the geometrical tachyon field that describe stable kink ...
متن کاملMetamorphosis Of Tachyon Profile In Unstable D9-Branes
We explored a variety of brane configurations in our previous paper within the two derivative truncation of the unstable D9-brane effective theory. In this paper we extend our previous results with emphasis on the inclusion of the higher derivative corrections for the tachyon and the gauge fields computed in the boundary string field theories. We give the exact solutions to BPS brane configurat...
متن کاملOn Tachyon Kinks from the Dbi Action
We consider solitonic solutions of the DBI tachyon effective action for a non-BPS brane in the presence of an electric field. We find that for a constant electric field Ẽ ≤ 1, regular solitons compactified on a circle admit a singular and decompactified limit corresponding to Sen’s proposal provided the tachyon potential satisfies some restrictions. On the other hand for the critical electric f...
متن کاملRegular and Periodic Tachyon Kinks
We search for regular tachyon kinks in an extended model, which includes the tachyon action recently proposed to describe the tachyon field. The extended model that we propose adds a new contribution to the tachyon action, which allows obtaining stable tachyon kinks of regular profile, which may appropriately lead to the singular kink found by Sen sometime ago. Also, under specific conditions w...
