Holographic Soliton Crystals for Dense Nuclear Matter and Neutron Stars
Lorenzo Bartolini, Sven Bjarke Gudnason, Jonas Mager +1
We construct a nuclear-matter equation of state (EOS) from holographic QCD in the Witten-Sakai-Sugimoto (WSS) model, going beyond the homogeneous ansatz by building dense baryonic…

Isospin asymmetry and neutron stars in V-QCD
Lorenzo Bartolini, Sven Bjarke Gudnason, Matti Järvinen
Isospin asymmetric nuclear matter is introduced to V-QCD, a bottom-up holographic Quantum Chromodynamics (QCD) model. Using a small isospin chemical potential we extract the symmet…

Neutron stars in the Witten-Sakai-Sugimoto model
Lorenzo Bartolini, Sven Bjarke Gudnason
We utilize the top-down holographic QCD model, the Witten-Sakai-Sugimoto model, in a hybrid setting with the SLy4, soft chiral EFT and stiff chiral EFT equations of state to descri…
