With the recent development of quantum gas microscopes, quantum simulators can now control ultracold atomic systems with single-site resolution.
Here, we present the progress towards a new strontium-based quantum simulator.
We have developed in-vacuum build-up optical cavities to create two-dimensional optical lattices with large mode waists using low input power. We characterized the lattice potential using clock spectroscopy in a non-magic lattice.
Additionally, we further present precision spectroscopy of the ultra-narrow magnetic quadrupole transition 1S0 - 3P2 in Sr. Using a magnetic field gradient, we managed to trap 88Sr atoms in a single two-dimensional layer within the optical lattice. Recently, our group successfully implemented single-site resolution fluorescence imaging of this two-dimensional layer.
By combining the advantage of a large system size and the realization of state-dependent optical lattices, we aim to emulate strongly coupled two-dimensional light-matter interfaces.
