Buchel, Alex; Langfelder, Peter; Walcher, Johannes Does the tachyon matter? (English) Zbl 1014.81045 Ann. Phys. 302, No. 1, 78-87 (2002). Summary: We study time-dependent solutions of Einstein-Maxwell gravity in four dimensions coupled to tachyon matter – the Dirac-Born-Infeld Lagrangian that provides an effective description of a decaying tachyon on an unstable D-brane in string theory. Asymptotically, the solutions are similar to the recently studied space-like brane solutions and carry \(S\)-brane charge. They do not break the Lorentzian \(R\)-symmetry. We study tachyon matter as a probe in such a background and analyze its backreaction. For early/late times, the tachyon field has a constant energy density and vanishing pressure as in flat space. On the other hand, at intermediate times, the energy density of the tachyon diverges and produces a space-like curvature singularity.
