Winding effects on brane/anti-brane pairs

Understand

We study a brane/anti-brane configuration which is separated along a compact direction by constructing a tachyon effective action which takes into account transverse scalars.

• Such an action is relevant in the study of HQCD model of Sakai and Sugimoto of chiral symmetry breaking, where the size of the compact circle sets the confinement scale.
• Our approach is motivated by string theory orbifold constructions and gives a route to model inhomogeneous tachyon decay.
• We illustrate the techniques involved with a relatively simple example of a harmonic oscillator on a circle.
