Tachyon Field in Intermediate Inflation
arXiv:0904.1032 · doi:10.1103/PhysRevD.79.083507
Abstract
The tachyonic inflationary universe model in the context of intermediate inflation is studied. General conditions for this model to be realizable are discussed. In the slow-roll approximation, we describe in great details the characteristics of this model.
