Symmetry of the crystal lattice can be a determining factor for the structure of Cooper pairs in unconventional superconductors. In this study we extend the discussion of superconductivity in noncentrosymmetric materials to the case when inversion symmetry is missing locally but is present on a global level. Concretely we investigate the staggered noncentrosymmetricity within a regular sublattice structure in some analogy to the discussion of superconductivity in antiferromagnetic systems. Three crystal structures are analyzed in detail as illustrative examples for the extended classification of Cooper pairing channels. One of the cases may be relevant for the class of iron pnictide superconductors. |
