A quantum field theory warm inflation model is presented that solves the horizon/flatness problems. The model obtains, from the elementary dynamics of particle physics, cosmological scale factor trajectories that begin in a radiation dominated regime, enter an inflationary regime and then smoothly exit back into a radiation dominated regime, with nonnegligible radiation throughout the evolution.

  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. Dark Matter as an Inflationary Relic in Warm Inflation

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

    In warm inflation with Υ∝T³, a residual inflaton condensate after rapid drop in Q evolves as cold dark matter with mass fixed at m≈0.02 MeV by the observed abundance.

  3. Inflationary Particle Production and the Swampland

    hep-th 2025-12 conditional novelty 6.0 of 10

    Tower-induced corrections to inflationary observables scale as (H/Λsp)^{2+p} and are negligible whenever H≪Λsp.
