Warm Inflation with Nonminimal Derivative Coupling by Kourosh Nozari, M. Shoukrani, N. Rashidi

“…We present a detailed calculation of the cosmological perturbations in this setup. We use the recent observational data from the joint data set of WMAP9 + BAO + H0 and also the Planck satellite data to constrain our model parameters for natural and chaotic inflation potentials. …”

Quantum Cosmology of Quadratic f(R) Theories with a FRW Metric by V. Vázquez-Báez, C. Ramírez

“…We study the quantum cosmology of a quadratic fR theory with a FRW metric, via one of its equivalent Horndeski type actions, where the dynamic of the scalar field is induced. …”

Mimetic Gravity: A Review of Recent Developments and Applications to Cosmology and Astrophysics by Lorenzo Sebastiani, Sunny Vagnozzi, Ratbay Myrzakulov

“…Mimetic gravity is a Weyl-symmetric extension of General Relativity, related to the latter by a singular disformal transformation, wherein the appearance of a dust-like perfect fluid can mimic cold dark matter at a cosmological level. Within this framework, it is possible to provide a unified geometrical explanation for dark matter, the late-time acceleration, and inflation, making it a very attractive theory. …”

Non-Gaussianity from Particle Production during Inflation by Neil Barnaby

“…In this review we show that interactions between the produced particles and the inflaton condensate can lead to a qualitatively new mechanism for generating cosmological fluctuations from inflation. We illustrate this effect using a simple prototype model g2(ϕ−ϕ0)2χ2 for the interaction between the inflaton, ϕ, and iso-inflaton, χ. …”

Warm non-minimally coupled Peccei–Quinn inflation and de Sitter Swampland conjecture by Jureeporn Yuennan, Phongpichit Channuie, Davood Momeni

“…Our model incorporates a PQ scalar field that is non-minimally coupled to gravity, facilitating inflation through a dissipative process that sustains a thermal bath, thereby distinguishing it from conventional cold inflation. …”

From de Sitter to de Sitter: Decaying Vacuum Models as a Possible Solution to the Main Cosmological Problems by G. J. M. Zilioti, R. C. Santos, J. A. S. Lima

“…Decaying vacuum cosmological models evolving smoothly between two extreme (very early and late time) de Sitter phases are able to solve or at least to alleviate some cosmological puzzles; among them we have (i) the singularity, (ii) horizon, (iii) graceful-exit from inflation, and (iv) the baryogenesis problem. …”

Noether Gauge Symmetry of Dirac Field in (2 + 1)-Dimensional Gravity by Ganim Gecim, Yusuf Kucukakca, Yusuf Sucu

Generalising axion-like particle as the curvaton: sourcing primordial density perturbation and non-Gaussianities by Anish Ghoshal, Abhishek Naskar

“…The ALP is a spectator field during inflation but it starts to oscillate and dominates the energy density of the universe after inflation ends, thereby sourcing isocurvature perturbations, while standard curvature fluctuations from the inflaton are assumed to be sub-dominant. …”
