Yb hybrid tweezer-lattice

We are developing a novel experimental platform for quantum simulation with ultracold fermionic Yb atoms. Our main goal is to realize novel techniques for local control in optical lattices by combining optical lattices with optical tweezer arrays.

Alkaline-earth-like atoms such as ytterbium offer a rich internal structure, including a long-lived metastable clock state and SU(N)-symmetric interactions, which make them a versatile resource for quantum simulation of lattice gauge theories and multi-orbital physics.

By combining a large-scale optical lattice with programmable optical tweezer arrays we aim at site-resolved preparation, control and detection of fermionic many-body states.
