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…
Unification of polynomial and exponential cosmological attractors
Renata Kallosh, Andrei Linde
We introduce a family of simple -attractor models that can interpolate between exponential and polynomial cosmological attractors. By varying the interpolation parameter in…
New Exponential and Polynomial -attractors
Renata Kallosh, Andrei Linde
We introduce a new family of cosmological attractors with non-minimal coupling of gravity and non-canonical kinetic terms. In the Einstein frame, these models transform into a clas…
