abstract

I show that the problem of realizing inflation in theories with random potentials of a limited number of fields can be solved, and agreement with the observational data can be naturally achieved if at least one of these fields has a non-minimal kinetic term of the type used in the theory of cosmological $\alpha$-attractors.

  1. Cosmological Constraints on Neutrino Masses in Quintessential Inflation

    astro-ph.CO 2026-02 conditional novelty 5.0 of 10

    In the α-attractor quintessential-inflation scenario, Planck PR4 + DESI DR2 BAO + Pantheon+ supernova data imply Σmν < 0.067 eV (flat) and <0.116 eV (with curvature).

  2. Forecasting constraints on quintessential inflation from future generation of galaxy and CMB surveys

    astro-ph.CO 2025-06 conditional novelty 4.0 of 10

    Future CMB and galaxy surveys are forecast to constrain the alpha-attractor quintessential inflation parameter to alpha = 2 ± 0.17 and the spectral index to n_s = 0.965 ± 0.0014.
