Radiofrequency spectroscopy of a strongly interacting two-dimensional Fermi gas
arXiv:1012.0049 · doi:10.1103/PhysRevLett.106.105301
Abstract
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 and find the existence of confinement-induced molecules in very good agreement with theoretical predictions.
