Universal thermal and electrical transport near the superconductor-metal quantum phase transition in nanowires. Physical Review B 77(18): 180501(R).1550-235Xhttp://nrs.harvard.edu/urn-3:HUL.InstRepos:7616484We describe the thermal (\(\kappa\)) and electrical (\(\sigma\)) conductivities of quasi-one-dimensional wires, across a quantum phase transition from a superconductor to a metal induced by pair-breaking perturbations. Fluctuation corrections to BCS theory motivate a field theory for quantum criticality. We describe deviations in the Wiedemann-Franz ratio \(\kappa∕\sigma T\) (where \(T\) is the temperature) from the Lorenz number \((\pi^2∕3)(k_B∕e)^2\), which can act as sensitive tests of the theory. We also describe the crossovers out of the quantum-critical region into the metallic and superconducting phases.en-USsuperconductivitystrongly correlated electronsJournal Article2012-01-1210.1103/PhysRevB.77.180501
