Speed of Sound in String Gas Cosmology
arXiv:0806.4358 · doi:10.1088/1126-6708/2008/09/082
Abstract
We consider an ensemble of closed strings in a compact space with stable one cycles and compute the speed of sound resulting from string thermodynamics. Possible applications to the issue of Jeans instability in string gas cosmology are mentioned.
