Self-Duality in Superconductor-Insulator Quantum Phase Transitions
arXiv:cond-mat/0002025 · doi:10.1103/PhysRevLett.85.3934
Abstract
It is argued that close to a Coulomb interacting quantum critical point, the interaction between two vortices in a disordered superconducting thin film separated by a distance changes from logarithmic in the mean-field region to in the region dominated by quantum critical fluctuations. This gives support to the charge-vortex duality picture of the observed reflection symmetry in the current-voltage characteristics on both sides of the transition.
