Hybrid -attractors, primordial black holes and gravitational wave backgrounds
Matteo Braglia, Andrei Linde, Renata Kallosh +1
We investigate the two-stage inflation regime in the theory of hybrid cosmological -attractors. The spectrum of inflationary perturbations is compatible with the latest Planck/B…
Goldstino Condensation?
Renata Kallosh, Andrei Linde, Timm Wrase +1
It was argued in \cite{DallAgata:2022abm} that the Volkov-Akulov (VA) model as well as similar models in supergravity and the related KKLT model in string theory, suffer from tachy…
Hybrid cosmological attractors
Renata Kallosh, Andrei Linde
We construct -attractor versions of hybrid inflation models. In these models, the potential of the inflaton field is uplifted by the potential of the second field . This…
Dilaton-Axion Inflation with PBHs and GWs
Renata Kallosh, Andrei Linde
We discuss two-stage dilaton-axion inflation models [1] and describe -attractor models with either exponential or polynomial approach to the plateau. We implement one of the mod…
Polynomial -attractors
Renata Kallosh, Andrei Linde
Inflationary -attractor models can be naturally implemented in supergravity with hyperbolic geometry. They have stable predictions for observables, such as , as…
BICEP/Keck and Cosmological Attractors
Renata Kallosh, Andrei Linde
We discuss implications of the latest BICEP/Keck data release for inflationary models, with special emphasis on the cosmological attractors which can describe all presently availab…
