Query: Deconfined, Massive Quark Phase at High Density and Compact Stars: A
  Holographic Study   In Hoyos et al. (arXiv:1603.02943) a holographic D3/D7 system was used to
describe a deconfined yet massive quark phase of QCD at finite density,
concluding that the equation of state of such a phase was not stiff enough to
support exotic dense stars. That analysis used a hard quark mass to represent
the dynamical mass and assumed a conformal gauge background. Here we
phenomenologically adjust the D3/D7 system to include a running anomalous
dimension for the quark condensate. This introduces a dynamical mechanism for
chiral symmetry breaking yet the model still has a deconfined massive phase at
intermediate densities. We show that these systems, dependent on the running
profile in the deep IR, generate much stiffer equations of state and
non-monotonic behaviour in the speed of sound. The results suggest that these
equations of state may be closer to supporting hybrid stars with quark cores.
