Non-Abelian topological order with SO(5)1 chiral edge states

We consider a chiral spin liquid constructed using the parton theory. This state supports non-Abelian anyons and neutral fermions, which share some similarities with the celebrated Moore-Read state. The edge physics of the parton state and the Moore-Read state is very different. Based on conformal field theory (CFT) analysis, it is proposed that the edge states exhibit an emergent SO(5) symmetry. The counting of edge states in the low-lying SO(5)1 CFT towers is computed. The chiral spin liquid is generated using tensor network methods, which allows us to confirm the SO(5)1 counting using entanglement spectrum. An additional feature of multiple branches in the entanglement spectrum is observed and analyzed.

Automated summary

In this study, a chiral spin liquid constructed using the parton theory is investigated. It is found that the edge physics of this state exhibits an emergent SO(5) symmetry, which is calculated by counting the edge states in the low-lying SO(5)1 CFT towers. The entanglement spectrum of the chiral spin liquid generated through tensor network methods confirms the SO(5)1 counting and reveals an additional feature of multiple branches.
