Mathematics and Physics of the Holographic Principle

Co-authors: Blaise Gouteraux (Nordita), Aristos Donos (Cambridge)

All scaling IR asymptotics in homogeneous, translation invariant holographic phases with a (potentially broken) U(1) symmetry in the IR are classified. The general critical saddle-point solutions are characterized by four critical exponents ($ heta, z$) for the metric as well as the scaling of the electric potential and electric flux . Neutral or charged geometries realizing both fractionalized or cohesive phases are found. In the presence of helical invariance, (breaking translational invariance), new universality classes are possible that correspond to insulators and bad metals.
