Abstract

We present a unified category-theoretic framework for quantum Hall hierarchy constructions and anyon superconductivity based on modular tensor categories over Rep(U(1))\mathrm{Rep}(\mathrm{U}(1)) and sRep(U(1)f)\mathrm{sRep}(\mathrm{U}(1)^f). Our approach explicitly incorporates conserved U(1)\mathrm{U}(1) charge and formulates doping via a generalized stack-and-condense procedure, in which an auxiliary topological order is stacked onto the parent phase, and the quasiparticles created by doping subsequently condense. Depending on whether this condensation preserves or breaks the U(1)\mathrm{U}(1) symmetry, the system undergoes a transition to a quantum Hall hierarchy state or to an anyon superconductor. For anyon superconductors, the condensate charge is determined unambiguously by the charged local bosons contained in the condensable algebra. Our framework reproduces all known anyon superconductors obtained from field-theoretic analyses and further predicts novel phases, including a charge-2e2e anyon superconductor derived from the Laughlin state and charge-keke anyon superconductors arising from bosonic Zk\mathbb{Z}_k Read-Rezayi states. By placing hierarchy transitions and anyon superconductivity within a single mathematical formalism, our work provides a unified understanding of competing and proximate phases near experimentally realizable fractional quantum Hall states.
