Description

We show that the 1𝐷 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 can host Majorana fermions. Neither a Rashba spin-orbit coupling nor an external magnetic field are required to produce such an effect.
