- 論文の詳細を見る
We report on the fundamental properties of superfluids with $d$-wave pairing symmetry. We consider neutral atomic Fermi gases in a harmonic trap, the pairing being produced by a Feshbach resonance via a $d$-wave interaction channel. A Ginzburg–Landau (GL) functional is constructed, which is symmetrically constrained for five component order parameters (OPs). We find OP textures in the cyclic phase and stability conditions for a non-Abelian fractional 1/3-vortex under rotation. We propose a method of creating the interesting 1/3-vortex experimentally in atomic gases by optical means.
