在光学晶格中实现并研究了二维费米原子强相互作用气体。利用射频光谱测量了强相互作用气体的相互作用能。我们在3D Feshbach共振的吸引端观察到了禁闭诱导的Feshbach共振，发现禁闭诱导分子的存在与理论预测非常一致。
We realize and study a strongly interacting two-component atomic Fermi gas confined to two dimensions in an optical lattice. Using radio-frequency spectroscopy we measure the interaction energy of the strongly interacting gas. We observe the confinement-induced Feshbach resonance on the attractive side of the 3D Feshbach resonance and find the existence of confinement-induced molecules in very good agreement with theoretical predictions.
