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…
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…
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…
ACT, SPT, and chaotic inflation
Renata Kallosh, Andrei Linde, Diederik Roest
We show that the simplest generalization of the chaotic inflation model with nonminimal coupling to gravity provides a good match to the results…
