  1. Nonlinear Lattice Framework for Inflation: Bridging stochastic inflation and the $\delta{N}$ formalism

    gr-qc 2026-04 unverdicted novelty 8.0

    A shear-free lattice method bridges stochastic inflation and δN formalism by enabling fully nonlinear calculations of curvature perturbations in single-field models with ultra-slow-roll phases.

  2. The statistics of curvature-profile dispersion in primordial black hole formation

    astro-ph.CO 2026-07 conditional novelty 7.0

    Rare coherent shape deformations of primordial curvature profiles can dominate primordial black hole abundance by lowering the collapse threshold enough to overcome their Gaussian statistical cost.

  3. The swallowed spike: the formation of light primordial black hole structures around heavy seeds

    astro-ph.CO 2026-06 unverdicted novelty 7.0

    Light PBHs around heavy primordial seeds form significantly less dense inner cores than particle DM because no studied torque mechanism prevents capture.

  4. Are Primordial Black Holes a Natural Dark Matter Candidate?

    hep-ph 2026-06 unverdicted novelty 7.0

    PBH dark matter spans all naturalness tiers, with some mechanisms as natural as WIMPs or freeze-in particles, determined by abundance map structure rather than candidate type.

  5. Gravitational Waves from Black Hole Reheating: The Scalar-Induced Component

    hep-ph 2026-05 unverdicted novelty 7.0

    Accounting for the minimal mass spread of primordial black holes from gravitational collapse suppresses the Poltergeist GW background to the level of generic scalar-induced signals and reopens ultra-light PBH parameter space.

  6. Gravitational wave emission from nonspherical collapse in an early matter-dominated era using N-body simulations

    astro-ph.CO 2026-05 unverdicted novelty 7.0

    Full numerical N-body treatment is required for reliable gravitational wave predictions from nonspherical collapse in early matter-dominated eras, with resulting spectra mappable to detector sensitivities via horizon ...

  7. A consistent formulation of stochastic inflation I: Non-Markovian effects and issues beyond linear perturbations

    astro-ph.CO 2026-05 unverdicted novelty 7.0

    The conventional truncation in stochastic inflation is inconsistent because quadratic-noise contributions are the same perturbative order as the deterministic non-Markovian corrections.

  8. Microscopic primordial black holes as macroscopic dark matter from large extra dimensions

    astro-ph.CO 2026-04 unverdicted novelty 7.0

    In the ADD extra-dimension model, microscopic primordial black holes undergo runaway accretion and grow to macroscopic scales, allowing them to comprise all dark matter with initial abundances as low as 10^{-44}.

  9. Constant-Roll Inflation: Analytical Formulae for Power Spectrum and Implications for Induced Gravitational Waves

    astro-ph.CO 2026-06 unverdicted novelty 6.0

    Analytical formulae for power spectrum peaks in constant-roll inflation enable parameter reconstruction from peak features and smoothed approximations for induced gravitational wave estimates.

  10. Opening the Window of Ultra-Light PBHs by Exorcising the Poltergeist

    hep-ph 2026-05 unverdicted novelty 6.0

    Incorporating the general-relativity mass tail df_PBH/d ln M ∝ M^3.78 smooths PBH evaporation, suppresses the scalar-induced GW signal by orders of magnitude, and reopens the ultra-light PBH window for the hot Big Bang.

  11. Isotropy, anisotropies and non-Gaussianity in the scalar-induced gravitational-wave background: diagrammatic approach for primordial non-Gaussianity up to arbitrary order

    astro-ph.CO 2025-05 unverdicted novelty 6.0

    Extends diagrammatic approach for scalar-induced gravitational waves to arbitrary-order local PNG, deriving semi-analytic spectra for energy density, anisotropies, bispectrum and trispectrum up to quartic terms.

  12. Hamiltonians to all Orders in Perturbation Theory and Higher Loop Corrections in Single Field Inflation with PBHs Formation

    astro-ph.CO 2025-02 unverdicted novelty 6.0

    Derives all-order Hamiltonians via EFT of inflation for USR models and shows L-loop corrections to CMB-scale perturbations scale as (ΔN P_e L)^L, exiting perturbative control at L=4 for typical ΔN≈2.5.

  13. Non-Perturbative Hamiltonian and Higher Loop Corrections in USR Inflation

    astro-ph.CO 2025-02 unverdicted novelty 6.0

    In USR inflation with an idealized instantaneous sharp transition to slow-roll, higher loop corrections to curvature perturbations on CMB scales grow rapidly with loop order L and may exit perturbative control.

    astro-ph.CO 2026-05 unverdicted novelty 5.0

    In excursion set theory with colored noises, the low-mass tail of the PBH mass function differs from Carr's formula because correlated noises end the degeneracy of formation probabilities, though Carr's formula remain...

  17. Inflation driven by repulsive-like primordial black holes

    gr-qc 2026-04 unverdicted novelty 5.0

    Repulsive-like primordial black holes in the Swiss-cheese framework produce quasi-de Sitter expansion, enabling inflation with evaporation reheating and acting as early dark energy for certain masses and densities.

    astro-ph.CO 2026-06 unverdicted novelty 4.0

    In mixed ULDM-PBH halos the continuum PBH contribution alters soliton structure at the tens-of-percent level while discrete shot noise induces mode transitions too slow to matter on galactic timescales.

    Bulk viscosity raises the critical collapse threshold for primordial black holes by an amount comparable to the viscosity strength and increases the resulting black hole masses.
