In the core of the vortex of a superconductor, energy levels appear inside the gap. We discuss here through a random matrix approach how these levels are broadened by impurities. It is first shown that the level statistics is governed by an ensemble consisting of a symplectic random potential added to a non-random matrix. A generalization of previous work(More)
We consider the effect of the Ruderman-Kittel-Kasuya-Yosida͑RKKY͒ interaction between magnetic impurities on the electron relaxation rates in a normal metal. The interplay between the RKKY interaction and the Kondo effect may result in a nonmonotonic temperature dependence of the electron momentum relaxation rate, which determines the Drude conductivity.(More)
We present fermi liquid expressions for the low temperature behavior of the superfluid stiffness, explain why they differ from those suggested recently by Lee and Wen, and discuss their applicability to data on high-T c super-conductors. We find that a consistent description requires a strong, doping dependent anisotropy, which affects states near the zone(More)
We consider a class of systems where, due to the large mismatch of dielectric constants, the Coulomb interaction is approximately one–dimensional. Examples include ion channels in lipid membranes and water filled nanopores in silicon films. Charge transport across such systems possesses the activation behavior associated with the large electrostatic(More)
