We review the theory of inflation with single and multiple fields paying particular attention to the dynamics of adiabatic and entropy/isocurvature perturbations which provide the primary means of testing inflationary models. We review the theory and phenomenology of reheating and preheating after inflation providing a unified discussion of both the gravitational and nongravitational features of multi-field inflation. In addition we cover inflation in theories with extra dimensions and models such as the curvaton scenario and modulated reheating which provide alternative ways of generating large-scale density perturbations. Finally we discuss the interesting observational implications that can result from adiabatic-isocurvature correlations and non-Gaussianity.

  1. Dilaton-Flattened Axion Inflation

    hep-ph 2026-04 unverdicted novelty 7.0

    Dilaton backreaction on an anomaly-inspired axion potential generates a closed-form Lambert-W flattened hilltop, giving r ≈ 0.033–0.036 and α_s ≈ −4.6×10^{-4} at N=56 with strictly adiabatic dynamics.

  2. Cosmic Inflation From Regular Black Holes

    gr-qc 2026-04 unverdicted novelty 7.0

    Regular black holes in the bulk of quasi-topological gravity drive a de Sitter inflationary phase on the brane at small scales, with e-fold number set by the ratio of black hole radius to higher-curvature scale.

  3. Multifield stochastic inflation: Relevance of number of fields in statistical moments

    astro-ph.CO 2026-05 unverdicted novelty 6.0

    Stochastic effects in multifield inflation make the number of fields relevant for e-fold statistics and power spectrum, with a general formula for higher moments and an upper bound on fields for successful inflation.

  4. Massive Exchange and the Sign of the Equilateral Bispectrum

    hep-th 2026-04 unverdicted novelty 6.0

    The equilateral bispectrum from massive scalar exchange in inflation is not universally negative in the full EFT of inflation; its sign depends on a critical ratio of operator coefficients.

  5. The Magnetic Origin of Primordial Black Holes: Ultralight PBHs and Secondary GWs

    astro-ph.CO 2026-05 unverdicted novelty 5.0

    Inflationary magnetic fields induce curvature perturbations that form ultralight PBHs, generating a stochastic GW background with model-specific features.

  6. Constraints on the inflationary vacuum and reheating era from NANOGrav

    astro-ph.CO 2026-05 unverdicted novelty 5.0

    NANOGrav data favors a blue-tilted tensor spectrum with nt ≈ 2.2, radiation-dominated reheating, and alpha-vacuum states over standard Bunch-Davies, with a frequency-dependent alpha suggested to resolve the blue-tilt tension.

  7. Analytic Approximations for Fermionic Preheating

    hep-ph 2026-04 unverdicted novelty 5.0

    Analytic approximations for fermion number density in λφ⁴ preheating scale as q^{1/2} for q ≲ 0.01 and q^{3/4} for q ≳ 10, with resonance peaks or half-filled Fermi spheres depending on the coupling.
