Inflation, the Hubble tension, and early dark energy: An alternative overview
W Giarè - Physical Review D, 2024 - APS
I review and discuss the possible implications for inflation resulting from considering new
physics in light of the Hubble tension. My study is motivated by a simple argument that the …

Tracking the multifield dynamics with cosmological data: a Monte Carlo approach
W Giarè, M De Angelis, C van de Bruck… - Journal of Cosmology …, 2023 - iopscience.iop.org
We introduce a numerical method specifically designed for investigating generic multifield
models of inflation where a number of scalar fields ϕ K are minimally coupled to gravity and …

Testing scale-invariant inflation against cosmological data
There is solid theoretical and observational motivation behind the idea of scale-invariance
as a fundamental symmetry of Nature. We consider a recently proposed classically scale …
