Quantum Metal--Superconductor Transition: A Local Field Theory Approach
arXiv:cond-mat/0404188 · doi:10.1103/PhysRevB.72.024514
Abstract
The zero temperature, or quantum, metal-superconductor phase transition is studied in disordered systems in dimension greater than two. A effective local field theory is developed that keeps all soft modes or fluctuations explicitly. A simple renormalization group analysis is used to exactly determine the quantum critical behavior at this transition.
