Gravitational Wave Background from Phantom Superinflation
arXiv:gr-qc/0601115 · doi:10.1103/PhysRevD.73.047302
Abstract
Recently, the early superinflation driven by phantom field has been proposed and studied. The detection of primordial gravitational wave is an important means to know the state of very early universe. In this brief report we discuss in detail the gravitational wave background excited during the phantom superinflation.
