Holography for heavy-ions collisions and quantum quenches

I. "Holography for heavy-ions collisions". Our goal is to obtain phenomenologically reliable insights for the physics of the quark-gluon plasma (QGP) from the holography. To fit the experimental form of the dependence of the total multiplicity on energy, obtained at LHC, we have to deal with a special anisotropic holographic model. This anisotropy leads to a non-sharp character of confinement/deconfinement phase transition line in the (\mu,T)-plane and changes holographic estimations of thermalization time, jet quenching, direct photon production etc.

II."Holography for bilocal quantum quenches". We discuss a similarity between thermalization in the holographic (1+1)-dimensional CFT after simultaneous generation of two high-energy excitations in the antipodal points on the circle (bilocal quench) and QGP formation in heavy-ions collisions. The holographic picture of such quantum quench is the creation of BTZ black hole from a collision of two massless particles. We perform holographic computation of entanglement entropy and mutual information in the boundary theory and analyze their evolution with time.
