Uniqueness of Tachyonic Solitons

TL;DR

This paper provides evidence from conformal field theory that tachyon condensation on bosonic D-branes leads to vacuum or soliton solutions independent of initial magnetic flux, supporting a key conjecture in string theory.

Contribution

It demonstrates a continuous path in open string configuration space connecting D-branes with different magnetic fluxes, confirming flux independence of tachyonic solitons.

Findings

Identified a continuous interpolation between D-branes with different magnetic fluxes.

Supported the conjecture that tachyon condensation results in flux-independent solutions.

Used conformal field theory techniques to analyze open string configurations.

Abstract

It has been conjectured that condensation of tachyons on a bosonic D-brane gives rise to vacuum / soliton solutions which are independent of the initial magnetic field on the D-brane. We present evidence for this conjecture using results from two dimensional conformal field theory. In particular we identify a continuous path in the configuration space of open string fields which interpolates between D-brane configurations with two different quantized magnetic flux.
