Microscopic origin of black hole entropy from tachyon condensation
Huiquan Li
We show generically that the dynamics of a probe particle near the event horizon of a non-extreme black hole is described by the tachyon effective action. The Hagedorn temperature…
Cosmological evolution of a D-brane
Huiquan Li
We study the cosmological evolution of a single BPS D-brane in the absence of potential, which is in the category of the Chaplygin gas cosmological model. When such a D-brane coupl…
Inhomogeneous tachyon condensation
Mark Hindmarsh, Huiquan Li
We investigate the spacetime-dependent condensation of the tachyon in effective field theories. Previous work identified singularities in the field which appear in finite time: inf…
Perturbations and moduli space dynamics of tachyon kinks
Mark Hindmarsh, Huiquan Li
The dynamic process of unstable D-branes decaying into stable ones with one dimension lower can be described by a tachyon field with a Dirac-Born-Infeld effective action. In this p…
