The superconducting wave function can have different symmetry, e.g. most/all low-temperature superconductors have s-wave symmetry (meaning the wave function amplitude is the same in all directions), whereas high-temperature superconductors have d-wave symmetry, which means the wave function amplitude has lobes and drops to zero along the diagonal axes. There are no p-wave superconductors to my knowledge (which I guess is meant when they talk about a 1D superconductor, i.e. the wave function has p-symmetry, but not even sure if that's what they mean).
I know the main researcher has brought forward a modified BCS theory that combines insulator-metal transition physics with superconductivity, no idea though what to make of that.

I.E. I understand it as a geometric limitation on the form of the crystals they can make. The theoretical stuff that got here implies it has d-wave symmetry, and so does the original paper.
