TLDR
In this article, a unified and general treatment of Starobinsky avatars of no-scale supergravity is presented, using the underlying non-compact SU(2, 1)/SU(2)×U(1) symmetry to demonstrate equivalences between different models, exhibiting 6 specific equivalence classes.Abstract:
Measurements of the cosmic microwave background (CMB) favour models of inflation with a small tensor-to-scalar ratio r, as predicted by the Starobinsky R + R2 model. It has been shown previously that various models based on no-scale supergravity with different forms of superpotential make predictions similar to those of the Starobinsky model. In this paper we present a unified and general treatment of Starobinsky avatars of no-scale supergravity, using the underlying non-compact SU(2,1)/SU(2)×U(1) symmetry to demonstrate equivalences between different models, exhibiting 6 specific equivalence classes.read more

Reheating and post-inflationary production of dark matter
TL;DR: In this paper, a systematic analysis of dark matter production during postinflationary reheating was performed, and it was shown that dark matter is sensitive to the inflaton potential and depends heavily on the maximum temperature when the universe becomes radiation dominated.

TL;DR: In this paper, the authors argue that the appropriate framework for cosmological inflation is that of no-scale supergravity, and show how to use supersymmetry in the context of supergravity.

TL;DR: In this article, the authors developed phenomenological and cosmological aspects of these no-scale attractor models that underpin their physical applications and derived the possible patterns of soft supersymmetry-breaking terms, which depend in $T$-type models whether the Polonyi and/or matter fields are twisted or not.

A new type of isotropic cosmological models without singularity
TL;DR: In this paper, the Einstein equations with quantum one-loop contributions of conformally covariant matter fields are shown to admit a class of nonsingular isotropic homogeneous solutions that correspond to a picture of the universe being initially in the most symmetric (de Sitter) state.

Particle Physics and Inflationary Cosmology
TL;DR: A monograph on inflationary cosmology and cosmological phase transitions is presented in this article, which investigates modern cosmology's relationship to elementary particle physics and includes a non-technical discussion of the theory for those unfamiliar with the theory.
