Topological Charge-2ne Superconductivity and Clustering Hierarchy
The authors develop a general framework to construct topological charge-2ne superconductors using two methods: generalizing Read-Green wavefunctions and breaking U(1) symmetry in fractional quantum Hall states. This framework reveals that higher-charge superconductivity supports richer topological phases than previously thought, including intrinsic fermionic non-Abelian order beyond charge-2e systems.
