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…
Mass and Isospin Breaking Effects in the Skyrme Model and in Holographic QCD
Lorenzo Bartolini, Stefano Bolognesi, Sven Bjarke Gudnason +1
We discuss how the quark masses and their mass splitting affect the baryons in the Skyrme model as well as the Witten-Sakai-Sugimoto (WSS) model. In both cases baryons are describe…
Symmetry energy in holographic QCD
Lorenzo Bartolini, Sven Bjarke Gudnason
We study the symmetry energy (SE), an important quantity in nuclear physics, in the Witten-Sakai-Sugimoto model and in a much simpler hard-wall model of holographic QCD. The SE is…
