Folding Branes

  title={Folding Branes},
  author={Omid Saremi and Lev Kofman and Amanda W. Peet},
We study classical dynamics of a probe D p -brane moving in a background sourced by a stack of D p -branes. In this context the physics is similar to that of the effective action for open-string tachyon condensation, but with a power-law runaway potential. We show that small inhomogeneous ripples of the probe brane embedding grow with time, leading to folding of the brane as it moves. We give a full nonlinear analytical treatment of inhomogeneous brane dynamics, suitable for the Dirac-Born…

Accelerating Branes and the String/Black Hole Transition

String theory in Euclidean flat space with a spacelike linear dilaton contains a D1-brane which looks like a semi-infinite hairpin. In addition to its curved shape, this ``hairpin brane'' has a

Dynamics of D1-brane in I-brane background

This paper is devoted to the study of the effective field theory description of the probe D1-brane in the background of the system of two stacks of fivebranes in type IIB theory that intersect on

Note About Non-BPS and BPS Dp-branes in Near Horizon Region of N Dk-Branes

In this paper we will consider the dynamics of BPS and non-BPS Dp-branes in the background of N Dk-branes. Our approach is based on an existence of the new symmetry of D-brane effective actions that

Geometrical tachyon kinks and NS5 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

Rolling down the throat in NS5-brane background: the case of electrified D-brane

We study rolling radion dynamics of electrified D-brane in NS5-brane background, both in effective field theory and in full open string theory. We construct exact boundary states and, from them,

Tubular solutions in NS5-brane, Dp-brane and macroscopic strings backgrounds

We present our searches for the tubular bound states of a D2-brane with m D0-branes and n fundamental strings in the NS5-brane, Dp-brane or macroscopic strings background by solving the

Non-BPS D-brane near NS5-branes

We use tachyon field theory effective action to study the dynamics of a non-BPS Dp-brane propagating in the vicinity of k NS5-branes. For the time dependent tachyon condensation we will concentrate

Geometrical tachyon dynamics in the background of a bulk tachyon field

We study the dynamics of a D3-brane moving in the background of a bulk tachyon field of a D3-brane solution of Type-0 string theory. We show that the dynamics on the probe D3-brane can be described

Fuzzy sphere dynamics and non-abelian DBI in curved backgrounds

We consider the non-Abelian action for the dynamics of NDp'-branes in the background of MDp-branes, which parameterises a fuzzy sphere using the SU(2) algebra. We find that the curved background

Late time behaviors of an inhomogeneous rolling tachyon

We study an inhomogeneous decay of an unstable D-brane in the context of Dirac-Born-Infeld (DBI)-type effective action. We consider tachyon and electromagnetic fields with dependence of time and one



Comments on D-brane dynamics near NS5-branes

We study the properties of a D-brane in the presence of k NS5 branes. The Dirac-Born-Infeld action describing the dynamics of this D-brane is very similar to that of a non-BPS D-brane in ten

Brane Inflation


We study dynamics of a D3-brane propagating in the vicinity of k coincident NS5 branes. We show that when gs is small, there exists a regime in which dynamics of the D-brane is governed by

A Geometric Interpretation of the Open String Tachyon

Unstable, non-BPS D-branes in weakly coupled ten dimensional string theory have many mysterious properties. Among other things, it is not clear what sets their tension, what is their relation to the

Inhomogeneous fragmentation of the rolling tachyon

Dirac-Born-Infeld type effective actions reproduce many aspects of string theory classical tachyon dynamics of unstable $\mathrm{D}p$-branes. The inhomogeneous tachyon field rolling from the top of

Scalar speed limits and cosmology: Acceleration from D-cceleration

Causality on the gravity side of the AdS/CFT correspondence restricts motion on the moduli space of the N = 4 super Yang Mills theory by imposing a speed limit on how fast the scalar field may roll.

Supersymmetric world-volume action for non-BPS D-branes

We construct the world-volume action for non-BPS D-branes in type II string theories. This action is invariant under all the unbroken supersymmetries in the bulk, but these symmetries are realised as
