Instanton Solution in Tachyon Cosmology

arXiv:0705.3291 · doi:10.1016/j.physletb.2007.06.046

Abstract

We find an exact classical solution in Euclidean gravity coupled to a scalar field with a particular form of potential commonly used in tachyon cosmology. This solution represents a tunneling between two vacua.
