揭示简谐势作用下冷原子超流体中的Majorana费米子态

Revealing Majorana Fermion states in a superfluid of cold atoms subject to a harmonic potential

Tao Zhou, Z. D. Wang

摘要:

本文研究了自旋轨道耦合和附加谐振子势作用下冷原子s波超流体中的Majorana费米子态。超流边界是由一个谐波势阱诱导的。基于自洽的Bogoliubov-de Gennes方程,数值计算了两个局域分离的Majorana费米子态。计算了局域态密度,通过局域态密度可以从实验上反映出Majorana激发的特征。

英文摘要:

We here explore Majorana Fermion states in an s-wave superfluid of cold atoms in the presence of spin-orbital coupling and an additional harmonic potential. The superfluid boundary is induced by a harmonic trap. Two locally separated Majorana Fermion states are revealed numerically based on the self-consistent Bogoliubov-de Gennes equations. The local density of states are calculated, through which the signatures of Majorana excitations may be indicated experimentally.
