We discuss the general structure and observational consequences of some of the simplest versions of chaotic inflation in supergravity in relation to the data by Planck 2013 and BICEP2. We show that minimal modifications to the simplest quadratic potential are sufficient to provide a controllable tensor mode signal and a suppression of CMB power at large angular scales.

  1. Effects of the ekpyrotic mechanism on inflationary phase in loop quantum cosmologies

    gr-qc 2025-10 conditional novelty 5.0 of 10

    In LQC and mLQC-I, tuned ekpyrotic-plus-inflation potentials can yield w>1 at the bounce and at least 60 e-folds of post-bounce inflation.

  2. The BAO-CMB Tension and Implications for Inflation

    astro-ph.CO 2025-07 accept novelty 5.0 of 10

    The upward shift in the scalar spectral index n_s in CMB+BAO analyses is driven by the combined effects of a known CMB degeneracy and the tension between CMB and DESI BAO data, not by new information about n_s itself.

  3. Large Field Polynomial Inflation in Palatini $f(R,\phi)$ Gravity

    astro-ph.CO 2024-11 conditional novelty 4.0 of 10

    Large-field polynomial inflation in Palatini f(R, phi) gravity can match Planck and BICEP/Keck data over broad parameter regions, and a negative R-squared coupling can suppress the tensor-to-scalar ratio to CMB-S4 levels.
