MgB2: superconductivity and pressure effects
V. A. Ivanov, J. J. Betouras, F. M. Peeters
We present a Ginzburg-Landau theory for a two-band superconductor with emphasis on MgB. Experiments are proposed which lead to identification of the possible scenarios: wheth…

Superconductivity with angular dependent coupling: stripes, Coulomb repulsion and enhanced Tc
V. V. Moshchalkov, V. A. Ivanov
We have analysed the effect of intrinsic doping inhomogeneity and the presence of stripes in high-T_c superconductors on coupling λby using a simple analytically solvable model wit…
