Disorder Protected and Induced Local Zero-Modes in Longer-Range Kitaev Chains

29 Apr 2018 Lieu Simon Lee Derek K. K. Knolle Johannes

We study the effects of disorder on a Kitaev chain with longer-range hopping and pairing terms which is capable of forming local zero energy excitations and, hence, serves as a minimal model for localization-protected edge qubits. The clean phase diagram hosts regions with 0, 1, and 2 Majorana zero-modes (MZMs) per edge... (read more)
