Abstract
Parafermion zero energy modes are a vital element of fault-tolerant topological quantum computation. Although it is believed that such modes form on the border between topological and normal phases, this has been demonstrated only for (Majorana) and parafermions. I consider an integrable model of one-dimensional fermions where such a demonstration is possible for parafermions with any . The procedure is easily generalizable for more complicated symmetry groups.
