摘要 文章基于描述零温超流费米气体的序参量方程,通过费曼传播子方法,解析了关闭光晶格和谐振子势后,超流费米原子气体的相干演化,以及仅关闭光晶格,费米超流在谐振子势中的周期演化。 Based on the order--parameter equation, we investigate the dynamics of superfluid Fermi gases released from both the harmonic trap and the one-dimensional optical lattice by means of the Feyn-man propagator method. We also investigate the dynamics of superfluid Fermi gases in the harmonic trap when only the optical lattice is switched off.
