Description:
Author(s): Hosho Katsura, Dirk Schuricht, and Masahiro Takahashi We study a system of interacting spinless fermions in one dimension that, in the absence of interactions, reduces to the Kitaev chain [Kitaev, Phys. Usp. 44 , 131 (2001) ]. In the noninteracting case, a signal of topological order appears as zero-energy modes localized near the edges. We show that the… [Phys. Rev.
