Fermi surfaces and nodal manifolds of 3D superconducting gaps discussed here. (Left) A type of state on a hole Fermi surface sheet which emerges from microscopic spin fluctuations calculations . (Center) A similar state on a hole Fermi sheet with horizontal line nodes which might explain the results of Ref. . (Right) The electron Fermi sheet. Solid blue lines represent gap nodes, while dashed blue lines represent deep gap minima.
