Query: Inhomogeneous superconductivity and the "pseudogap state of novel
  superconductors   Novel superconducting compounds such as the high Tc oxides are intrinsically
inhomogeneous systems. An inhomogeneous structure is created by doping and the
statistical nature of the distribution of dopants. Consequently, the critical
temperature is spatially dependent: Tc = Tc (r).
