Topological Solitons Seminar: From holography towards real-world nuclear matter

Presented by Andreas Schmitt , University of Southampton

10 February 2016 13:00 in CM221

Quantum Chromodynamics is notoriously difficult to solve at nonzero baryon density, and most models or effective theories of dense quark or nuclear matter are restricted to a particular density regime and/or a particular form of matter. I will present a study of dense (and mostly cold) matter within the holographic Sakai-Sugimoto model where baryons are realized as instantons. I will and discuss the question
whether two basic properties of real-world cold and dense matter are reproduced,
a first-order onset of nuclear matter and a chiral phase transition at high density to quark matter.
A model of strongly-coupled matter with these two properties would be extremely useful for astrophysical applications because it would provide a single equation of state for all densities relevant in a compact star.
