Jointly modelling Cosmic Inflation and Dark Energy

Abstract

Quintessential inflation utilises a single scalar field to account for the observations of both cosmic inflation and dark energy. The requirements for modelling quintessential inflation are described and two explicit successful models are presented in the context of $\alpha$-attractors and Palatini modified gravity.
