Proposal for Realizing Majorana Fermions Without External Magnetic Field in Strongly Correlated Nanowires / K.K.Kesharpu, E.A.Kochetov, A.Ferraz // Physical Review B [Electronic resource]. – 2024. – Vol. 109, No. 11. – P. 115140. – URL: https://doi.org/10.1103/PhysRevB.109.115140. – Bibliogr.: 99.

We show that one-dimensional topological superconductivity can be placed in the context of phenomena associated with strongly correlated electron systems. Here we propose a system consisting of a one-dimensional chain of strongly correlated fermions placed on a superconducting (SC) substrate that exhibits a spin-singlet extended s-wave pairing. Strong electron correlation is shown to transform an extended s-wave SC into a topological SC that hosts Majorana fermions. In contrast to the approaches based on mean-field treatments, no Zeeman or exchange magnetic field is needed to produce such an effect.
