Nonlinear Properties of the BCS Gap Equation

  • Chapter
Microscopic Aspects of Nonlinearity in Condensed Matter

Part of the book series: NATO ASI Series ((NSSB,volume 264))

Abstract

The iterative solution of the BCS gap equation defines a nonlinear map, which can be studied with the tools developed for nonlinear dynamics. We demonstrate the usefulness of this approach in determining the phase diagram in the superconducting state, in the presence of a non-trivial pairing interaction, having mixed s and d-wave symmetry.
