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-singular…
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…
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…
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…
Attractors in Supergravity
Renata Kallosh, Andrei Linde
The concept of attractors, well-known in classical mechanics, proved to be very productive in supergravity, in the theory of black holes and inflationary cosmology. We start with a…
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 o…
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…
