We propose a field theory for describing the tachyon on a brane-antibrane system near the minimum of the potential. This field theory realizes two known properties of the tachyon effective action: 1) absence of plane-wave solutions around the minimum, and 2) exponential fall off of the pressure at late time as the tachyon field evolves from any spatially homogeneous initial configuration towards the minimum of the potential. Classical solutions in this field theory include non-relativistic matter with arbitrary spatial distribution of energy.

    Tachyon EFT near its minimum is mapped via collective field theory to a coherent-state subsector of Klein-Gordon theory, indicating quantum-level equivalence between open and closed string descriptions of unstable D-b...
