We study strongly supercooled cosmological phase transitions. We perform numerical lattice simulations of two-bubble collisions and demonstrate that, depending on the scalar potential, in the collision the field can either bounce to a false vacuum or remain oscillating around the true vacuum. We study if these cases can be distinguished from their gravitational wave signals and discuss the possibility of black hole formation in the bubble collisions.

  1. Vacuum bubbles from cosmic ripples

    hep-ph 2026-04 conditional novelty 6.0 of 10

    Over-densities in the early universe reduce the Euclidean action for vacuum decay, making false-vacuum bubbles nucleate earlier; under-densities do the opposite.

  2. Numerical simulations of primordial black hole formation via delayed first-order phase transitions

    gr-qc 2026-01 conditional novelty 6.0 of 10

    Spherically symmetric numerical relativity shows false-vacuum domains from delayed first-order phase transitions form type B (baby-universe) or type A (direct-collapse) primordial black holes, separated by a robust t_...

  3. Complementary Probes of Warped Extra Dimension: Colliders, Gravitational Waves and Primordial Black Holes from Phase Transitions

    hep-ph 2025-02 conditional novelty 6.0 of 10

    In Randall-Sundrum warped extra dimension models, the supercooled radion phase transition can form primordial black holes that account for all of dark matter for IR scales 10 TeV to 10^4 TeV, with correlated gravitati...

  4. What happens when supercooling is terminated by curvature flipping of the effective potential?

    hep-ph 2024-12 conditional novelty 6.0 of 10

    Supercooling terminated by curvature flipping still proceeds by bubble nucleation and expansion, not by smooth phase mixing, according to 3D lattice simulations.
