Interplay between the holographic QCD phase diagram and mutual & $n$-partite information

Understand

In earlier work, we studied holographic entanglement entropy in QCD phases using a dynamical Einstein-Maxwell-dilaton gravity model whose dual boundary theory mimics essential features of QCD above and below deconfinement.

• The model although displays subtle differences compared to the standard QCD phases, however, it introduces a notion of temperature in the phase below the deconfinement critical temperature and captures quite well the entanglement and thermodynamic properties of QCD phases.
• Here we extend our analysis to study the mutual and $n$-partite information by considering $n$ strips with equal lengths and equal separations, and investigate how these quantities leave their imprints in holographic QCD phases.
• We discover a rich phase diagram with $n\geq2$ strips and the corresponding mutual and $n$-partite information shows rich structure, consistent with the thermodynamical transitions, while again revealing some subtleties.
