Figure 1

The nearest neighbouring interactions of 2N Majorana sites described by the “superconducting” chain.

Each solid line represents a Majorana site and the crossing means the interaction. The dashed line divides the interactions into two parts that are described by and respectively. When , , the first line and the last line are free and the Hamiltonian corresponds to topological phase.
