Time-reversal invariant parafermions in interacting Rashba nanowires
Time-reversal invariant parafermions in interacting Rashba nanowires
We propose a scheme to generate pairs of time-reversal invariant parafermions. Our setup consists of two quantum wires with opposite Rashba spin orbit interactions coupled to an $s$-wave superconductor, in the presence of electron-electron interactions. The zero-energy bound states localized at the wire ends arise from the interplay between two …
