Abstract: The dynamics of quantum field theories with global symmetries simplify considerably in the limit of large conserved charges. I will discuss the analogous limit in theories with gauge symmetries by focusing on the Abelian Higgs model relevant to the description of type II superconductors at criticality. In particular, I will show how the approach allows identifying the appropriate non-local order parameter for the superconducting phase transition and computing the corresponding eta critical exponent in a novel double scaling limit.
