Symmetry energy from holographic QCD

We review the symmetry energy in the context of AdS/CFT correspondence. After constructing D-brane configurations corresponding to dense system in boundary theory, we calculate the symmetry energy by solving DBI action of D branes in confining and deconfining phase. We conclude that the density dependence of the symmetry energy has scaling law, whose power depends only on the dimensionality of the branes and space-time.
