概要
- 論文の詳細を見る
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.
