Phase transition and entropy of quantum entanglement

A holographic model of QCD will be considered, which makes it possible to describe the experimental dependence of the total multiplicity of particles formed during collisions of heavy ions, as well as to make predictions about the nature of the phase transition confinement/ confinement. The model is based on constructing black holes/branes solutions in 5-dimensional dilaton gravity, interacting with Maxwell fields. A possible experimental check of this type models will be discussed. It will be shown that in the case of ultra-peripheral collisions, the entropy of entanglement of overlapping Glauber regions grows with isotropization. The dependence on the anisotropy parameter of energy losses and other observables will be also discussed.
