Description
The ability to address atoms or emitters locally is among the most important capabilities of quantum gases experiments. Cavity QED methods for detection and manipulation, by singling out one or a set of modes determined by the geometry, usually sacrifice spatial resolution in favor of enhanced sensitivity or strong non-linearities. I will describe two experiments in which we demonstrate local measurements and addressing of atoms in a high-finesse cavity. In the first one, I will show the direct, in-situ observation of the self-organization transition in a unitary Fermi gas under side-pumping. In the second, I will describe a new device combining a high-finesse cavity and a microscope in a single optical element, that allows for the local control over light-matter interaction. I will then discuss some of the perspectives that these systems open for analogue quantum simulation.
