Towards time-resolved, weakly-destructive measurements of strongly interacting Fermi gases. — •Kevin Roux, Barbara Cilenti, Oscar Bettermann, and Jean-Philippe Brantut — Ecole Polytechnique Federale de Lausanne (EPFL), Lausanne, Switzerland

We present the design of a new apparatus aimed at trapping an ultracold gas of fermionic lithium in a high-finesse optical resonator. The optical cavity will serve as a deep, far off resonant dipole trap, allowing for efficient capture and evaporative cooling, and as a measurement tool. With a high finesse for close to resonance light, the cavity will allow to perform weakly destructive measurements of slow transport processes, following the density evolution in real time, with a signal to noise ratio approaching the single atom sensitivity. We plan to apply this technique to measure low currents through mesoscopic channels (both 1D and 2D). The cavity could also be used to induce long range, photon mediated interactions leading to a rich phase diagram. We will present the general design of the system and the progresses of the experimental setup.
