A Raman-Induced Feshbach Resonance in a Single-Component Fermi Gas



Ian B. Spielman, Ross Williams, Matthew Beeler, Lindsay J. LeBlanc, Karina Jimenez-Garcia


Ultracold gases of interacting spin-orbit coupled fermions are predicted to display exotic phenom- ena such as topological superfluidity and its associated Majorana fermions. Here, we experimentally demonstrate a route to strongly-interacting single-component atomic Fermi gases by combining an s-wave Feshbach resonance (giving strong interactions) and spin-orbit coupling (creating an effective p-wave channel). We identify the Feshbach resonance by its associated atomic loss feature and show that, in agreement with our single-channel scattering model, this feature is preserved and shifted as a function of the spin-orbit coupling parameters.
