In this chapter we first describe the early history of primordial black hole (PBH) research. We then discuss their possible formation mechanisms, including critical collapse from inflationary fluctuations and various types of phase transition. We next describe the numerous constraints on the number density of PBHs from various quantum and astrophysical processes. This was the main focus of research until recently but there is currently a shift of emphasis to the search for evidence for PBHs. We end by discussing this evidence, with particular emphasis on their role as dark matter candidates, sources of gravitational waves and seeds for supermassive black holes and early cosmic structures.

  1. Primordial black hole in Lorentz-violating theories: Insights from Bumblebee gravity

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Bumblebee gravity enhances primordial black hole abundance through three mechanisms, but the model harbors a ghost instability and a tachyonic instability that make it cosmologically unviable.

  2. The Quantum Mechanics of Rare Events: From Quantum Walks to Stochastic Inflation

    hep-th 2026-08 conditional novelty 5.0 of 10

    Rare fluctuations in quantum walks are ruled by a measurement-induced relative entropy, and applying this to stochastic inflation yields a steady state that violates detailed balance.

  3. A simple mechanism for the enhancement of the inflationary power spectrum

    astro-ph.CO 2026-02 conditional novelty 5.0 of 10

    Two-stage, two-field inflation with a simple quadratic-plus-interaction potential produces repeated field-space turns that amplify the curvature power spectrum by several orders of magnitude.
