The open energy spectrum for the case of three Majorana chains. (a) The effect of NN hopping term in the topological phase with two α and one β Majorana zero modes at each end. (b) The effect of NNN hopping term in the topological phase with two α Majorana fermions at each end. The parameters in (a) are: \({t}_{1}^{^{\prime} }=0.3,\,{t}_{2}^{^{\prime} }=0.9\) and in (b) are: \({t}_{1}^{^{\prime} }=0.9,\,{t}_{2}^{^{\prime} }=0.3\), η 1 = 0.1. The other parameters are t 1 = 0.2, t 2 = 1, \({t}_{1}^{^{\prime\prime} }=0.4,\,{t}_{2}^{^{\prime\prime} }=0.8\). The insets schematically show the left boundary zero modes in the absence of the symmetry breaking terms.
