摘      要：We study the topological properties of the one-dimensional non-Hermitian Kitaev model with complex either periodic or quasiperiodic *** obtain the energy spectrum and the phase diagrams of the system by using the transfer matrix method as well as the topological *** phase transition points are given *** Majorana zero modes in the topological nontrivial regimes are *** on the quasiperiodic potential,we obtain the phase transition from the topological superconducting phase to the Anderson localization,which is accompanied with the Anderson localization–delocalization transition in this non-Hermitian *** also find that the topological regime can be reduced by increasing the non-Hermiticity.
