Schematic illustration of the model Eq. (1) (upper) with the period: (a) T = 2; (b) T = 4. The red (pink) circles represent Majorana fermions α (β). The lower ones schematically illustrate the corresponding models in terms of fermions (blue circles). The energy spectrum on an open chain as a function of φ: (c) T = 2; (d) T = 4. The winding number as a function of φ: (e) T = 2; (f) T = 4. The parameter λ = 0.6 is used.
