On Tachyon Kinks from the Dbi Action
نویسنده
چکیده
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 field Ẽ = 1, regular and finite energy solitons are constructed without any restriction on the potential.

Inhomogeneous tachyon condensation
We investigate the spacetime-dependent condensation of the tachyon in effective field theories. Previous work identified singularities in the field which appear in finite time: infinite gradients at the kinks, and (in the eikonal approximation) caustics near local minima. By performing a perturbation analysis, and with numerical simulations, we demonstrate and explain key features of the conden...
متن کاملTachyon Effective Actions In Open String Theory
We argue that the Dirac-Born-Infeld (DBI) action coupled to a tachyon, that is known to reproduce some aspects of open string dynamics, can be obtained from open string theory in a certain limit, which generalizes the limit leading to the usual DBI action. This helps clarify which aspects of the full open string theory are captured by this action.
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...
متن کاملEntropy and Quantum States of Tachyon Supertube
We quantize the deformed modes of a single supertube solution with regular profile of circular cross section on the unstable non-BPS D3-branes by using the Minahan-Zwiebach tachyon action. The result is used to count the microstates in an ensemble of supertube with fixed macroscopic quantities of charges QD0, QF1 and angular momentum J . We show that the entropy of the system is proportional to...
متن کاملTachyon condensation and universality of DBI action
We show that a low-energy action for massless fluctuations around a tachyonic soliton background representing a codimension one D-brane coincides with the Dirac-Born-Infeld action. The scalar modes which describe transverse oscillations of the D-brane are translational collective coordinates of the soliton. The appearance of the DBI action is a universal feature independent of details of a tach...
