We show that it is extremely difficult and perhaps even impossible to have inflation supported by thermal effects.

  1. Heterotic Warm Inflation

    hep-th 2025-09 conditional novelty 7.0 of 10

    In a heterotic-string-inspired two-field warm inflation model, the axion drives inflation while thermal corrections from gauge fields block sustained dilaton-driven inflation.

  2. Warm Inflation with Pseudo-scalar Couplings

    hep-ph 2025-05 unverdicted novelty 7.0 of 10

    Warm inflation models with pseudo-scalar couplings require inclusion of induced chemical potentials that make the thermal friction-fluctuation relation model-dependent rather than universal.

  3. One Feature, Three Clocks: Phase-Locked Gravitational Waves, Primordial Black Holes, and Non-Gaussianity from Periodic Warm Inflation

    astro-ph.CO 2026-06 unverdicted novelty 6.0 of 10

    Periodic warm inflation imprints one log-periodic feature on the curvature spectrum that saturates asteroid-mass PBHs, generates dual-band GW backgrounds, and offsets the bispectrum phase by a quarter cycle fixed by s...

  4. From inflation to hot big bang -- a tutorial on cosmological perturbations

    hep-ph 2026-07 accept novelty 1.0 of 10

    A tutorial deriving cosmological perturbation equations from inflation through reheating, with explicit gauge-invariant computations and Python scripts.
