We explore the role of phase fluctuations in a three-dimensional s-wave superconductor, NbN, as we approach the critical disorder for destruction of the superconducting state. Close to critical disorder, we observe a finite gap in the electronic spectrum which persists at temperatures well above T(c). The superfluid density is strongly suppressed at low temperatures and evolves towards a linear...
Quasiclassical Green's functions of a short superconductor/normal metal/superconductor (SNS) junction are calculated for multi-mode junction with arbitrary electron transmission properties. They provide the basis for description of all of the junction transport characteristics , and are used to calculate the equilibrium spectral density of supercurrent fluctuations.

We study mesoscopic fluctuations in the supercurrent of a Josephson junction consisting topological insulator microbridge between two conventional superconductors. In model, we account for strong proximity effect when superconductors induce gap spectrum surface states as well magnetic field piercing area that causes depairing and filling. The overall magnitude functional form current are determ...
We report the results of low temperature transport, specific heat, and magnetization measurements on high quality single crystals of the bilayer perovskite Sr3Ru2O7, which is a close relative of the unconventional superconductor Sr2RuO4. Metamagnetism is observed, and transport and thermodynamic evidence for associated critical fluctuations is presented. These relatively unusual fluctuations mi...
