| Abstract: | It has recently been observed that MgB2 is a superconductor with a high transition temperature.Here the authors propose a model of anisotropic s-wave superconductivity which consistently describes the observed properties of this compound,including the thermodynamic and optical response in sintered MgB2 wires.The authors also determine the shape of the quasiparticle density of states and the anisotropy of the upper critical field and the superfluid density. |
