Post-inflationary enhancement of adiabatic perturbations in modular cosmology
Rodrigo Gonzalez Quaglia, Martino Michelotti, Diederik Roest +3
We show that multi-field inflationary models with negligible turning in field space during inflation can lead to an effective sourcing of adiabatic from entropic perturbations {\it…

Axion Stabilization in Modular Cosmology
John Joseph Carrasco, Renata Kallosh, Andrei Linde +1
The invariant -attractor models have plateau potentials with respect to the inflaton and axion fields. The potential in the axion direction is almost exactly…
