Entanglement entropy in SU(N) gauge theories


I discuss the entanglement entropy in SU(N) lattice gauge theories. The entanglement entropy is studied exactly in 1+1 space-time dimensions and in Migdal-Kadanoff approximation in higher dimensional space. The existence of a non-analytical behavior reminiscent of a phase transition for a characteristic size of the entangled region is demonstrated for higher dimensional theories.
