提出了空间调制的超流体相或富尔德-费雷尔-拉金-奥夫钦尼科夫态可以在最近实现的共振费米子原子凝聚中观测到。我们通过解决理想的一维和现实的三维情况下的Bogoliubov-de Gennes方程来检查最佳实验设置。通过光学吸收或施特恩-格拉赫实验，可以直接将这种超流体的自发调制成像为密度分布。
It is proposed that the spatially modulated superfluid phase, or the Fulde-Ferrell-Larkin-Ovchinnikov state could be observed in resonant fermion atomic condensates which are realized recently. We examine optimal experimental setups to achieve it by solving the Bogoliubov-de Gennes equation for both idealized one-dimensional and realistic three-dimensional cases. The spontaneous modulation of this superfluid is shown to be directly imaged as the density profiles either by optical absorption or by Stern-Gerlach experiments.
