To USR or not to USR: An effective description of two-field dynamics
Samuel Sánchez López, Eemeli Tomberg
Single-field models of inflection point inflation experience a phase of ultra-slow roll (USR), leading to amplified curvature perturbations. Recently, Lorenzoni et al. modified the…
Non-oscillating Early Dark Energy and Quintessence from Alpha-Attractors
Lucy Brissenden, Konstantinos Dimopoulos, Samuel Sánchez López
Early dark energy (EDE) is one of the most promising possibilities in order to resolve the Hubble tension: the discrepancy between early and late-Universe measurements of the Hubbl…
Modelling Quintessential Inflation in Palatini Modified Gravity
Konstantinos Dimopoulos, Alexandros Karam, Samuel Sánchez López +1
We study a model of quintessential inflation constructed in modified gravity with a non-minimally coupled scalar field, in the Palatini formalism. Our non-minimal inflaton fi…
