Quantum Hall hierarchy and anyon superconductivity

I study how anyon condensation connects quantum Hall phases and unconventional superconductors, using categorical methods, effective field theories, and explicit wave functions.

Topological data and physical constraints

I classify anyon statistics and study what they imply for chiral edge transport, intrinsic sign problems, and microscopic realizations of topological phases.
