A phenomenology analysis of the tachyon warm inflation in loop quantum cosmology

TL;DR

This paper explores how tachyon warm inflation behaves within loop quantum cosmology, revealing differences in inflation duration and timing compared to classical models, especially under varying dissipative regimes.

Contribution

It provides a phenomenological analysis of tachyon warm inflation in loop quantum cosmology, highlighting the effects of dissipation strength on inflation dynamics.

Findings

In strong dissipation, total e-folds are fewer than classical predictions.

In weak dissipation, warm inflation starts later than tachyon cool inflation.

The model uses an exponential potential for the tachyon field.

Abstract

We investigate the warm inflation condition in loop quantum cosmology. In our consideration, the system is described by a tachyon field interacted with radiation. The exponential potential function, $V(\phi)=V_0 e^{-\alpha\phi}\label{exp-p}$, with the same order parameters $V_0$ and $\alpha$, is taken as an example of this tachyon warm inflation model. We find that, for the strong dissipative regime, the total number of e-folds is less than the one in the classical scenario, and for the weak dissipative regime, the beginning time of the warm inflation will be later than the tachyon (cool) inflation.
