Waterfall-modulated -attractors
Renata Kallosh, Andrei Linde, Yusuke Yamada
Hybrid -attractor models \cite{Kallosh:2022ggf} can have significantly greater values of and smaller , while preserving the relation , which is va…
Quintessential α-attractors, updated
Renata Kallosh, Andrei Linde, Marina Shmakova +1
Quintessential -attractor models of single-field inflation and evolving dark energy were constructed about a decade ago. Recently, it was pointed out that some of them might be…
Inflation, Open Universes, and Dark Energy
Anton Chudaykin, Mikhail M. Ivanov, Renata Kallosh +3
We study the impact of spatial curvature () and dynamical dark energy (parametrized by and ) on the spectral index using a combination of cosmic microwave bac…
The BAO-CMB Tension and Implications for Inflation
Elisa G. M. Ferreira, Evan McDonough, Lennart Balkenhol +3
The scalar spectral index is a powerful test of inflationary models. The tightest constraint on to date derives from the combination of cosmic microwave background (CMB…
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…
