OPTICAL CONTROL OF INTERACTIONS IN FERMI GAS QUANTUM SIMULATORS
Abstract
The proposed program exploits new, broadly applicable, optical techniques for designer temporal, spatial, and momentum-selective control of atom-atom interactions in quantum simulators comprising ultracold, optically-trapped Fermi gases. In the past, optical control methods employing a single far-detuned optical fi eld have been shown to provide only limited tunability of the interaction strength, due to excited state spontaneous emission, which produces heating and inelastic loss. The new methods, which we have developed under AFOSR support, employ two optical fields to greatly suppress spontaneous emission, by creating destructive quantum interference near a two-photon resonance, i.e., electromagnetically induced transparency. As previously demonstrated in a multi-component Fermi gas of 6Li, these general two-fi eld methods optimize the trade-off between tunability and loss, by controlling the interaction strength with only small changes in the optical frequencies near the minimum loss point.
