Primordial black holes could potentially form during a first-order cosmological phase transition due to a build-up of particles which are predominantly reflected from the advancing bubble walls. After discussing the general mechanism, we examine the criteria that need to be satisfied for a black hole to form. We then set out the Boltzmann equation that describes the evolution of the relevant phase space distribution function, carefully describing our treatment of the Liouville operator and the collision term. Assuming a spherical false vacuum pocket of sufficient size and a constant wall velocity, we find that black holes can form in a range of different scenarios.

Can the universe be matter-dominated after a supercooled first-order phase transition?
After a supercooled first-order phase transition, the scalar field's equation of state is set by the bubble-wall Lorentz factor γ*, and matter domination is delayed until a/a* ≃ γ* in the free-streaming limit.

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

Baryogenesis via Asymmetric Evaporation of Primordial Black Holes
Evaporating primordial black holes, biased by a new gravitational interaction, can reproduce the observed baryon asymmetry once entropy dilution and chemical-potential-dependent emission are included.

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

What happens when supercooling is terminated by curvature flipping of the effective potential?
Supercooling terminated by curvature flipping still proceeds by bubble nucleation and expansion, not by smooth phase mixing, according to 3D lattice simulations.

Primordial Black Holes (as Dark Matter) from the Supercooled Phase Transitions with Radiative Symmetry Breaking
Supercooled radiative symmetry breaking phase transitions generically produce primordial black holes, and the false-vacuum decay rate grows exponentially with time to high accuracy.

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

Super-exponential Primordial Black Hole Production via Delayed Vacuum Decay
PBH abundance from delayed vacuum decay follows f_pbh ≈ M exp(-Q exp(-S3(Tp)/Tp)), so S3(Tp)/Tp super-exponentially controls how many black holes form.

Supercooled Phase Transitions with Radiative Symmetry Breaking
Supercooled phase transitions from radiative symmetry breaking can be described, at leading and next-to-leading order, by formulas depending only on three or four parameters (χ0, β̄, g, and g̃ at NLO).
