Holography and the Dynamics of Strongly Coupled Dense Matter

The thesis    will focus on applications of the holographic gauge/gravity duality to the description of the dense state of strongly interacting  matter, and in particular to static and dynamical properties of neutron stars. The thesis work will consist in constructing models for the baryonic phase of holographic QCD (based on the V-QCD class of theories)  at high density; in studying the corresponding equilibrium equation of state and phase diagram; in  constructing realistic models which interpolate between the holographic approach at high density (well above nuclear saturation density) and nuclear physics models at lower densities. The out of equilibrium dynamics  of the corresponding phases will be investigated, with a  a particular emphasis on linking the theoretical description with observations of (proto)neutron star formation in mergers and core-collapse supernovae via multi-messenger signals. An important aspect will be the description of neutrino transport through the dense medium.
