Fractional topological superconductivity and parafermion corner states by Katharina Laubscher, Daniel Loss, Jelena Klinovaja

“…We show that in such a system strong electron-electron interactions can stabilize a helical topological superconducting phase hosting Kramers partners of Z_{2m} parafermion edge modes, where m is an odd integer determined by the position of the chemical potential. …”

Majorana and parafermion corner states from two coupled sheets of bilayer graphene by Katharina Laubscher, Daniel Loss, Jelena Klinovaja

“…In particular, we find that the system supports a fractional topological insulator phase exhibiting fractionally charged gapless edge states and a fractional second-order topological superconducting phase exhibiting zero-energy Z_{2m} parafermion corner states, where m is an odd integer determined by the position of the chemical potential.…”
