This chapter provides a review of the frameworks developed for cosmological perturbation theory in loop quantum cosmology, and applications to various models of the early universe including inflation, ekpyrosis and the matter bounce, with an emphasis on potential observational consequences. It also includes a discussion on extensions to include non-Gaussianities and background anisotropies, as well as on its limitations concerning trans-Planckian perturbations and quantization ambiguities. It concludes with a summary of recent work studying the relation between loop quantum cosmology and full loop quantum gravity.

  1. Asymmetric Quantum Oppenheimer-Snyder Collapse

    gr-qc 2026-08 conditional novelty 6.0 of 10

    Asymmetric loop-quantum-cosmology collapse of a dust ball yields a geodesically complete, bouncing regular black hole spacetime with a C^0 shock at the dust surface and two joined vacuum geometries.

  2. Lessons from gauge fixing and polymerization of loop quantum black holes with a cosmological constant

    gr-qc 2025-02 accept novelty 6.0 of 10

    Constant-polymerization loop quantization of Schwarzschild-de Sitter in Kantowski-Sachs gauge generates a spurious low-curvature black hole horizon, while Schwarzschild-anti-de Sitter does not.

  3. Quantum Damping of Cosmological Shear: A New Prediction from Loop Quantum Cosmologies

    gr-qc 2025-10 reject novelty 5.0 of 10

    In mLQC-I, Bianchi I shear is claimed to decay exponentially after the bounce, producing isotropization independent of the matter content.

  4. Effects of the ekpyrotic mechanism on inflationary phase in loop quantum cosmologies

    gr-qc 2025-10 conditional novelty 5.0 of 10

    In LQC and mLQC-I, tuned ekpyrotic-plus-inflation potentials can yield w>1 at the bounce and at least 60 e-folds of post-bounce inflation.

  5. Einstein@Home all-sky "bucket" search for continuous gravitational waves in LIGO O3 public data

    gr-qc 2025-08 unverdicted novelty 4.0 of 10

    A non-detection and upper limit for continuous gravitational waves is claimed, but the body text is an unrelated cosmology paper, making the result unverifiable.
