${\mathbb{Z}}_4$ Parafermions \& the $8\pi$-periodic Josephson effect in interacting Rashba nanowires

Chris J. Pedder, Tobias Meng, Rakesh P. Tiwari +1

We demonstrate the appearance of zero-energy bound states satisfying the ${\mathbb{Z}}_4$ parafermionic algebra in interacting quantum wires with Rashba spin-orbit coupling and proxi…
