Holographic QCD, entanglement entropy, and critical temperature

Abstract

Based on gauge-gravity duality, by using holographic entanglement entropy, we have done a phenomenological study to probe the confinement-deconfinement phase transition in the holographic model resembling quantum chromodynamics with two massless flavors and three colors. Our outcomes are in perfect agreement with the expected results, qualitatively and quantitatively. We find out that the (holographic) entanglement entropy is a reliable order parameter for probing the phase transition.
