| 摘要: | The anisotropic Fermi superfluid of ultra-cold Fermi atoms under the p-wave Feshbach resonance is studied theoretically. The pairing symmetry of the ground state is determined by the strength of the atom-atom magnetic dipole interaction. It is kz for a strong dipole interaction; while it becomes kz−iβky, up to a rotation about ẑ, for a weak one. (Here β<1 is a numerical coefficient.) By changing the external magnetic field or the atomic gas density, a phase transition between these two states can be driven. We discuss how the pairing symmetry of the ground state can be determined in the time-of-flight experiments. |
