Abstract
We consider a layered superconductor with a complex order parameter wh ose phase switches sign from one layer to the next. This system is sho wn to exhibit gapless superconductivity for sufficiently large interla yer pairing or interlayer hopping. In addition, this description is co nsistent with experiments finding signals of time reversal symmetry br eaking in high-temperature superconductors only at the surface and not in the sample bulk.
