We introduce a new phenomenological one-scale model for the evolution of domain wall networks, and test it against high-resolution field theory numerical simulations. We argue that previous numerical estimates of wall velocities are inaccurate, and suggest a more accurate method of measurement. We show that the model provides an adequate approximation to the evolution of key parameters characterizing the evolution of the network. We use the model to study possible scaling solutions for domain wall networks, and discuss some of their cosmological consequences.

  1. Domain walls through different cosmologies

    astro-ph.CO 2026-07 accept novelty 6.5 of 10

    Domain-wall network area scales as S ≈ 2ξV/τ with ξ≈1.2 across cosmologies from dust to near-Minkowski, so the particle horizon—not H⁻¹—sets the correlation length and GW peak.

  2. Biased Domain Wall Networks and their Gravitational Waves

    astro-ph.CO 2026-07 conditional novelty 6.0 of 10

    Population-biased domain wall networks annihilate at T_ann ~ T_s B_s^0.8 and emit a single-broken-power-law gravitational-wave spectrum peaking near twice the Hubble scale.

  3. Dynamical criterion for biased domain-wall formation

    hep-ph 2026-06 unverdicted novelty 6.0 of 10

    Derives dynamical criterion for biased domain wall formation by evaluating p_fv at freeze-out temperature T_fo, producing stricter condition than conventional static threshold and consistency condition T_fo > T_ann.

  4. Collapsing domain walls with $\mathbb{Z}_2$-violating coupling to thermalized fermions and their impact on gravitational wave detections

    hep-ph 2025-01 conditional novelty 6.0 of 10

    Thermal corrections from a Z2-violating Yukawa coupling alter domain-wall annihilation temperatures and can change predicted gravitational wave spectra by orders of magnitude.
