The energy-momentum tensor of perturbed tachyon matter

The energy-momentum tensor of perturbed tachyon matter

We add an initial nonhomogeneous perturbation to an otherwise homogeneous condensing tachyon background and compute its space time energy-momentum tensor from worldsheet string theory. We show that in the far future the energy-momentum tensor corresponds to nonhomogeneous pressureless tachyon matter...
