From: Topological quantum criticality in non-Hermitian extended Kitaev chain
Zero mode solutions plotted with respect to the parameter \(\lambda _1\) shows both \(W = 0\) to \(W = 1\) \((\lambda _2 = 0.5)\) and \(W=1\) to \(W=2\) \((\lambda _2 = 2.0)\) topological phase transitions. Blue dots (p1 and p2) represent the transition points. The ZMS, \(X_{+}\) (red) and \(X_{-}\) (blue) are plotted in y-axis.
