Holographic modeling of nuclear matter and neutron stars

Understand

I review holographic models for (dense and cold) nuclear matter, neutron stars, and their mergers.

• I start by a brief general discussion on current knowledge of cold QCD matter and neutron stars, and go on discussing various approaches to model cold nuclear and quark matter by using gauge/gravity duality, pointing out their strengths and weaknesses.
• Then I focus on recent results for a complex bottom-up holographic framework (V-QCD), which also takes input from lattice QCD results, effective field theory, and perturbative QCD.
• Dense nuclear matter is modeled in V-QCD through a homogeneous non-Abelian bulk gauge field.
