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…

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…

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…
