# Defective Majorana zero modes in a non-Hermitian Kitaev chain

@article{Zhao2021DefectiveMZ, title={Defective Majorana zero modes in a non-Hermitian Kitaev chain}, author={Xiao-Ming Zhao and Cuixian Guo and Su-Peng Kou and Lin Zhuang and Wu-Ming Liu}, journal={Physical Review B}, year={2021} }

We investigate the number-anomalous of the Majorana zero modes in the non-Hermitian Kitaev chain, whose hopping and superconductor paring strength are both imbalanced. We find that the combination of two imbalanced non-Hermitian terms can induce defective Majorana edge states, which means one of the two localized edge states will disappear due to the non-Hermitian suppression effect. As a result, the conventional bulk-boundary correspondence is broken down. Besides, the defective edge states…

Observation of Majorana fermions in ferromagnetic atomic chains on a superconductor

High-resolution spectroscopic imaging techniques show that the onset of superconductivity, which gaps the electronic density of states in the bulk of the Fe chains, is accompanied by the appearance of zero-energy end-states, providing strong evidence for the formation of a topological phase and edge-bound Majorana fermions in atomic chains.
