# Warm Quintessential Inflation

## TL;DR

This paper proposes a warm quintessential inflation model that unifies early universe inflation and current dark energy, naturally reheating the universe and fitting observational data.

## Contribution

It introduces a warm inflation framework for quintessential inflation, addressing reheating and observational consistency in a unified model.

## Key findings

- Successfully accounts for inflation and dark energy observations
- Naturally reheats the universe, solving a key problem
- Operates in the weak dissipative regime

## Abstract

We introduce warm quintessential inflation and study it in the weak dissipative regime. We consider the original quintessential inflation model, which approximates quartic chaotic inflation at early times and thawing quartic inverse-power-law quintessence at present. We find that the model successfully accounts for both inflation and dark energy observations, while it naturally reheats the Universe, thereby overcoming a major problem of quintessential inflation model-building.
