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…
Inflation, Open Universes, and Dark Energy
Anton Chudaykin, Mikhail M. Ivanov, Renata Kallosh +3
The authors analyze how allowing a small negative spatial curvature and/or a time‑varying dark energy equation of state changes the inferred scalar spectral index nₛ from CMB and g…
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 i…
Streamlined Supergravity
Renata Kallosh, Andrei Linde
The textbook N=1 supergravity has an F-term potential depending on a superpotential and a Kahler potential , with the scalar potential $V(z^i, \ba…
Singular -attractors
Renata Kallosh, Andrei Linde
-attractor models naturally appear in supergravity with hyperbolic geometry. The simplest versions of -attractors, T- and E-models, originate from theories with non-singula…
On the Present Status of Inflationary Cosmology
Renata Kallosh, Andrei Linde
We give a brief review of the basic principles of inflationary theory and discuss the present status of the simplest inflationary models that can describe Planck/BICEP/Keck observa…
