Thermal Tachyon Cosmology

TL;DR

This paper explores a high-temperature thermal phase in multi D-brane systems that precedes tachyon inflation, potentially impacting early universe cosmology despite its brief duration.

Contribution

It introduces the concept of a thermal cosmological phase in multi D-brane systems occurring before tachyon inflation, a novel idea in brane cosmology.

Findings

Identification of a thermal phase prior to tachyon inflation.

Potential applications for early universe cosmology.

Brief duration but significant implications for brane cosmology.

Abstract

We show that in a multi D\={D} branes system with high temperature, there may exist a thermal cosmological phase before usual tachyon inflation. Though this thermal phase can be very transitory, it may has some interesting applications for early tachyon/brane cosmology.
