研究了费米原子气体p波共振超流体中，核中伴随Majorana零模的奇异涡旋的稳定性条件。在Ginzburg-Landau框架下，我们确定了外旋频率和谐波陷阱频率在参数空间中的稳定条件。在这个参数空间中，准二维凝聚体存在一个狭窄的稳定区域。我们还详细描述了旋光作用下手征p波超流体序参量的空间结构。
The stability conditions for the singular vortex that accompanies Majorana zero modes at the core are investigated for p -wave resonant superfluids of atomic Fermi gases. Within the Ginzburg–Landau framework, we determine the stable conditions in the parameter space for the external rotation frequency and the harmonic trap frequency. There exists a narrow stable region in this parameter space for quasi-two-dimensional condensates. We also describe the detailed characterizations of the spatial structure of the order parameter in the chiral p -wave superfluids under rotation.
