Phases of cold holographic QCD: baryons, pions and rho mesons
Nicolas Kovensky, Aaron Poole, Andreas Schmitt
We improve the holographic description of isospin-asymmetric baryonic matter within the Witten-Sakai-Sugimoto model by accounting for a realistic pion mass, computing the pion cond…
Building a realistic neutron star from holography
Nicolas Kovensky, Aaron Poole, Andreas Schmitt
We employ the recently improved description of dense baryonic matter within the Witten-Sakai-Sugimoto model to construct neutron stars. In contrast to previous holographic approach…
Isospin asymmetry in holographic baryonic matter
Nicolas Kovensky, Andreas Schmitt
We study baryonic matter with isospin asymmetry, including fully dynamically its interplay with pion condensation. To this end, we employ the holographic Witten-Sakai-Sugimoto mode…
Strange quark mass turns magnetic domain walls into multi-winding flux tubes
Geraint W. Evans, Andreas Schmitt
Dense quark matter is expected to behave as a type-II superconductor at strong coupling. It was previously shown that if the strange quark mass is neglected, magnetic domain…
Chiral pasta
Andreas Schmitt
Interiors of neutron stars are ultra-dense and may contain a core of deconfined quark matter. Such a core connects to the outer layers smoothly or through a sharp microscopic inter…
Heavy Holographic QCD
Nicolas Kovensky, Andreas Schmitt
We study the phase structure of the Witten-Sakai-Sugimoto model in the plane of temperature and baryon chemical potential, including the effect of a nonzero current quark mass. Our…
