Topological Superconductivity in a Weyl model of stacked Su-Schrieffer-Heeger chains

In a previous publication, using quantum Monte Carlo and mean-field theory,  we had studied conventional superconductivity in a Weyl system of stacked Su-Schrieffer-Heeger (SSH) chains. In the present paper, we study a Weyl model of stacked SSH chains by introducing a simple and natural pairing term which couples different sublattices.  We find topological superconductivity featuring Majorana states along the boundary perpendicular to the direction of the Su-Schrieffer-Heeger dimerization.
