In this review article, we describe the role of holography in deciphering the physics of dense QCD matter, relevant for the description of compact stars and their binary mergers. We review the strengths and limitations of the holographic duality in describing strongly interacting matter at large baryon density, walk the reader through the most important results derived using the holographic approach so far, and highlight a number of outstanding open problems in the field. Finally, we discuss how we foresee holography contributing to compact-star physics in the coming years.

  1. Holographic Soliton Crystals for Dense Nuclear Matter and Neutron Stars

    hep-ph 2026-07 conditional novelty 7.0 of 10

    A crystal of holographic baryons in the Witten-Sakai-Sugimoto model yields a nuclear-matter equation of state compatible with neutron-star observations.

  2. Locating the QCD critical point with neutron-star observations

    astro-ph.HE 2025-06 conditional novelty 6.0 of 10

    Bayesian analysis of a hybrid holographic EOS with neutron-star constraints locates the QCD critical endpoint at μ≈626 MeV and T≈119 MeV and predicts a strong first-order deconfinement transition at zero temperature.

  3. Testing the effective action approach to bubble nucleation in holography

    hep-th 2025-07 conditional novelty 5.0 of 10

    A two-derivative holographic effective action reproduces critical bubble solutions from the full gravity theory to within a few percent across thin-wall and thick-wall regimes.
