Abstract
Current cavity QED experiments are becoming a promising platform for quantum simulation of models of fermionic superfluidity. In this setting, the collective dipole of the atomic array generated by atom-photon interactions is a measure of the superfluid order parameter. Here, we discuss a protocol that can enhance the superfluid coherence dynamically by making the photons resonant with some of the atoms in the array.
