Inflation from a Tachyon Fluid?
Malcolm Fairbairn, Michel H.G. Tytgat (ULB)
TL;DR
This paper investigates the conditions under which a universe dominated by tachyon matter can undergo inflation, focusing on the early dynamics of a single tachyon field in a flat, homogeneous setting.
Contribution
It provides an analysis of the inflationary conditions specific to tachyon fields, extending previous theoretical work on tachyon cosmology.
Findings
Identifies conditions necessary for tachyon-driven inflation.
Analyzes the early evolution of a tachyon-dominated universe.
Highlights differences from standard scalar field inflation.
Abstract
Motivated by recent works of Sen and Gibbons, we study the evolution of a flat and homogeneous universe dominated by tachyon matter. In particular, we analyse the necessary conditions for inflation in the early roll of a single tachyon field.
