Towards Quantum Simulation of Light-Matter Interfaces with Strontium Atoms in Optical Lattices — •Valentin Klüsener1,2, Jan Trautmann1,2, Dimitry Yankelev1,2, Annie J. Park1,2, Immanuel Bloch1,2,3, and Sebastian Blatt1,2 — 1MPQ, Hans-Kopfermann-Str. 1, 85748 Garching, Germany — 2MCQST, Schellingstr. 4, 80799 München, Germany — 3LMU, Schellingstr. 4, 80799 München, Germany
In the last two decades, quantum simulators based on ultracold atoms in optical lattices have successfully emulated strongly correlated condensed matter systems. With the recent development of quantum gas microscopes, these quantum simulators can now control such systems with single-site resolution. Within the same time period, atomic clocks have also started to take advantage of optical lattices by trapping alkaline-earth-metal atoms such as Sr, and interrogating them with unprecedented precision and accuracy. Here, we report on progress towards a new quantum simulator that combines quantum gas microscopy with optical lattice clock technology. We have developed in-vacuum buildup cavities with large mode volumes that will be used to overcome the limits to system sizes in quantum gas microscopes. In addition, we present precision spectroscopy of the ultra-narrow magnetic quadrupole transition 1S0 – 3P2 in Sr, which enables spatially selective addressing in an optical lattice. By combining these techniques with state-dependent lattices, we aim to emulate strongly-coupled light-matter-interfaces.
