Interplay between the holographic QCD phase diagram and entanglement entropy

Understand

In earlier work, we introduced a dynamical Einstein--Maxwell--dilaton model which mimics essential features of QCD (thermodynamics) below and above deconfinement.

• Although there are some subtle differences in the confining regime of our model as compared to the standard results, we do have a temperature dependent dual metric below $T_c$ as well, allowing for a richer and more realistic holographic modeling of the QCD phase structure.
• We now discuss how these features leave their imprints on the associated entanglement entropy when a strip region is introduced in the various phases.
• We uncover an even so rich structure in the entanglement entropy, consistent with the thermodynamical transitions, while again uncloaking some subtleties.
