Abstract

The critical dynamics of superconductors is studied using renormalization group and duality arguments. We show that in extreme type-II superconductors the dynamic critical exponent is given exactly by z=3∕2. This result does not rely on the widely used models of critical dynamics. Instead, it is shown that z=3∕2 follows from the duality between the extreme type-II superconductor and a model with a critically fluctuating gauge field. Our result is in agreement with Monte Carlo simulations and at least one experiment.
