We evaluate the probability that a loop of string that has spontaneously nucleated during inflation will form a black hole upon collapse, after the end of inflation. We then use the observational bounds on the density of primordial black holes to put constraints on the parameters of the model. Other constraints from the distortions of the microwave background and emission of gravitational radiation by the loops are considered. Also, observational constraints on domain wall nucleation and monopole pair production during inflation are briefly discussed.

  1. Compact space catalysis of false vacuum decay and Schwinger effect

    hep-th 2026-05 unverdicted novelty 7.0 of 10

    For spatial volumes below a critical value in D compact dimensions, a new bounce distinct from Coleman's O(D) bubble mediates false vacuum decay, yielding homogeneous configurations and enhanced rates.

  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. Primordial black hole formation in bulk-viscous cosmology

    gr-qc 2026-06 unverdicted novelty 4.0 of 10

    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.

  4. Evolution of interior entropy of a loop quantum-corrected black hole pierced by a cosmic string

    gr-qc 2024-12 conditional novelty 4.0 of 10

    For a large-mass loop-quantum-corrected black hole pierced by a cosmic string, the paper derives the evolution relation between interior entropy and Bekenstein-Hawking entropy and shows the total satisfies the second law.
