Advances in the holographic description of hot and dense QCD matter
Nicolas Kovensky, Andreas Schmitt
We review and extend recent progress on QCD-like phases at nonzero temperature and chemical potentials within the gauge-gravity duality. We focus on the Witten-Sakai-Sugimoto model…
Nuclear chiral density wave in neutron stars?
Orestis Papadopoulos, Andreas Schmitt
Anisotropic phases potentially play a role in the internal composition of neutron stars, the main laboratory for the phase structure of QCD at high baryon densities. We review the…
Softening holographic nuclear matter
Christian Ecker, Nicolas Kovensky, Orestis Papadopoulos +1
Baryons in the holographic Witten-Sakai-Sugimoto model are described by instanton solutions on the flavor branes. A commonly used approximation for dense baryonic matter replaces t…
How neutron star properties disfavor a nuclear chiral density wave
Orestis Papadopoulos, Andreas Schmitt
Cold and dense matter may break rotational symmetry spontaneously and thus form an anisotropic phase in the interior of neutron stars. We consider the concrete example of an anisot…
Thermal pion condensation: holography meets lattice QCD
Nicolas Kovensky, Andreas Schmitt
The holographic Witten-Sakai-Sugimoto model is often employed to describe strongly-coupled baryonic and isospin-asymmetric matter, for example in the context of neutron stars. Here…
