Density Functional Theory of the Superconducting State
Traditional superconductivity of pure metals is well described as a phenomenon of homogeneous media. Due to the relatively large coherence length (102 – 104 Å), inhomogeneities on the scale of the lattice constant can be neglected. In the new high-T c materials the situation is different. Experimental coherence lengths of the order of 10 Å suggest that inhomogeneities on the scale of the lattice constant have to be taken into account in a proper description of these materials.
