| 摘 要： | 通过数值求解Bogoliubov de Gennes方程，研究了具有自旋轨道耦合作用的一维费米晶格系统的性质．结果表明：在有限的自旋轨道耦合下和一定的磁场强度时，系统具有零能，此时的准粒子即为Majorana费米子．准无序效应研究表明，Majorana费米子不会被弱准无序所破坏．

| Abstract: | It was studied the properties of one-dimensional fermionic atomic systems of spin-orbital couplings by means of numerically solving the Bogoliubov de Gennes equations. It was showed that, under the finite spin-orbital coupling strength and strong enough magnetic field, the system would be of zero energy, which be-haved as the Majorana fermions. The effects of the quasi-disorder on the Majorana wave functions were also studied, which had little influence on the localization of the Majorana fermions. |
