    ℤ N duality and parafermions revisited by Zhihao Duan, Qiang Jia, Sungjay Lee

    Published 2023-11-01
    “…We generalize this story to two-dimensional theories with non-anomalous ℤ N symmetry, focusing on parafermionization. We find the generic operators defining different topological boundary states including orbifolding and parafermionization with ℤ N or subgroups of ℤ N , and discuss their algebraic properties as well as the ℤ N duality web.…”

    Exceptional points in the Baxter-Fendley free parafermion model by Robert A. Henry, Murray T. Batchelor

    Published 2023-07-01
    “…Certain spin chains, such as the quantum Ising chain, have free fermion spectra which can be expressed as the sum of decoupled two-level fermionic systems. Free parafermions are a generalisation of this idea to $\mathbb{Z}_N$-symmetric clock models. …”
