Coupled Even-Parity Superconducting States: Square Lattice.
Abstract
The Ginzburg-Landau free energy density for the coupling of s-wave and d-wave superconducting states in square planar symmetry is considered. Four single-order parameter states and a mixed state are enumerated along with analytical relations for their thermodynamic critical fields, Hc, and critical temperatures. The differential Ginzburg-Landau equations are derived and applied to the calculation of the upper and lower critical fields, Hc2 and Hcl. The relevance of the analysis to superconductivity in the Cu-O planes of the high-Tc materials is discussed. Keywords: Superconducting states, Coupled even parity, Square lattice, Ginzburg Landau theory, Free energy, s-Waves, d-Waves.
