Parafermions in polarized $\nu=2/3$ Fractional Quantum (Anomalous) Hall Heterostructures

Motivated by recent experimental signatures of fractional Chern insulators in 2D quantum materials, we investigate the realization of $\mathbb Z_3$ parafermion zero modes (PZMs) on edges of spin-polarized $\nu=2/3$ fractional quantum Hall states which are proximitized by superconductors. Unlike the spin-unpolarized Hal...
