Quantum superconductor-metal transition
arXiv:cond-mat/0004058 · doi:10.1103/PhysRevB.64.132502
Abstract
We consider a system of superconducting grains embedded in a normal metal. At zero temperature this system exhibits a quantum superconductor-normal metal phase transition. This transition can take place at arbitrarily large conductance of the normal metal.
