First order phase transitions (FOPTs) are usually described by the nucleation and expansion of new phase bubbles in the old phase background. While the dynamics of new phase bubbles have been extensively studied, a comprehensive treatment of the shrinking old phase remnants remained undeveloped. We present a novel formalism for remnant statistics in FOPTs and perform the first analytical calculations of their distribution. By shifting to the reverse time description, we identify the shrinking remnants with expanding old phase bubbles, allowing a quantitative evolution and determination of the population statistics. Our results not only provide essential input for cosmological FOPT-induced soliton/primordial black hole formation scenarios, but can also be readily applied to generic FOPTs.

  1. Gravitational Waves From Dark Binaries With Finite-Range Dark Forces

    gr-qc 2024-12 conditional novelty 7.0 of 10

    A finite-range dark force between dark-matter binaries sharpens and enhances the predicted gravitational wave background, adding knee features tied to the mediator mass.

  2. Primordial black holes from Q-balls produced in a first-order phase transition

    hep-ph 2025-05 conditional novelty 6.0 of 10

    Bosons trapped in false-vacuum remnants of a dark first-order phase transition can form Q-balls that collapse into primordial black holes, producing correlated gravitational-wave and gamma-ray signals.

  3. Gravitational waves from supercooled phase transitions in conformal Majoron models of neutrino mass

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A detailed scan of conformal U(1)' Majoron models finds that supercooled phase transitions produce gravitational waves detectable by LIGO, LISA, and ET, and that current null data already exclude part of the parameter space.

  4. PBH formation and Gravitational Waves as Multi-messenger Signals of First-order Phase Transitions

    hep-ph 2026-07 conditional novelty 5.0 of 10

    False-vacuum collapse during first-order phase transitions can form PBHs and emit GWs across a broad parameter range, and MeV-scale classically conformal U(1)_{B-L} symmetry breaking has the largest region where both ...

  5. Populating dark sectors with relativistic bubble walls

    hep-ph 2024-12 conditional novelty 3.0 of 10

    Relativistic bubble walls can pair-produce dark matter much heavier than the phase transition scale, which then free-streams as warm dark matter.
