Ultracold quantum gases provide an opportunity to engineer Hamiltonians that model condensed matter phenomena in a well-controlled environment. Strontium, being an alkaline-earth element, has narrow intercombination lines, metastable excited electronic states, and ten collisionally-stable SU(N)-symmetric nuclear spin states. These properties open new perspectives for Hamiltonian engineering, studying quantum simulation of many-body systems and quantum optics.
To enrich the existing toolbox to manipulate Sr atoms, we have determined the frequency of the mHz-linewidth 1S0-3P2 transition to within 250 kHz relative to molecular iodine lines. This transition is useful for quantum simulation since it enables nuclear spin state dependent light shifts, Raman couplings, and more. We are currently integrating a microscope objective into our apparatus, which will initially enable the preparation and detection of single Sr atoms in optical tweezers and ultimately will lead to a Sr quantum gas microscope.
