Expérimental
We offer an experimental internship in the field of ultracold atoms and quantum simulation. We study degenerate atomic gases, produced by laser cooling techniques and arranged on a periodic structure created by interfering laser beams. This setting leads to the production of strongly correlated fermions, prone to collective quantum phenomena such as magnetism and entanglement. In the search for quantum effects, typically, environments are considered detrimental, sources of decoherence. However, in specific cases, couplings to an environment can actually produce and stabilize non-trivial states. This exciting new idea means that quantum phenomena may be harvested for quantum simulation or sensing (clocks, atom interferometers) in a more robust manner than formerly thought. Our system is suited to explore both sides of the problem: Hamiltonian evolution towards entangled states, driven by anti-ferromagnetic interactions and coherent spin manipulations, and dissipative control. The intern will join during experiments in the Hamiltonian regime. In parallel, he/she will build a new laser system targeting the ultranarrow clock line of strontium, enabling a whole new set of schemes to measure quantum correlations. The internship is meant to act as introduction for a PhD on dissipative control. By introducing photo-association losses, we aim at demonstrating the robust production of a new set of quantum-correlated states, and at investigating their advantages for quantum sensors.
