Contribution

It introduces a new interpretation linking thermodynamic Bethe ansatz boundary entropy with tachyon dynamics in boundary string field theory.

Findings

Boundary entropy in massless flows correlates with tachyon energy.

Temperature in TBA formalism maps to tachyon energy near the UV fixed point.

Provides a framework for understanding string vacuum stability.

Abstract

We put forward an idea that the boundary entropy associated with integrable massless flow of thermodynamic Bethe ansatz (TBA) is identified with tachyon action of boundary string field theory. We show that the temperature parameterizing a massless flow in the TBA formalism can be identified with tachyon energy for the classical action at least near the ultraviolet fixed point, i.e. the open string vacuum.
