We are interested in studying the properties of exotic quantum many-body systems using quantum simulation. Our main interest are:
Quantum simulation of lattice gauge theories
Topological many-body systems
Anomalous Floquet topological systems
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.
This is a collaboration with the group of Monika Aidelsburger. We have built a new Quantum Gas Microscope experiment with bosonic Caesium atoms at LMU to study topological many-body phases of matter. We will make use of the unique possibilities offered by high-resolution imaging techniques to investigate topological many-body phenomena in these lattices.
Our experimental setup consists of a 39K BEC in an optical honeycomb lattice. The lattice is formed by three propagating, s-polarized, blue-detuned laser beams at a wavelength of 745nm, which interfere in the xy-plane at relative angles of 120°.
Neutral-atom arrays have gained increasing importance in the development of quantum computing architectures. More recently, high-fidelity single- and two-qubit operations have also been demonstrated with alkaline-earth(-like) atoms AELA, which offer unique opportunities for high-fidelity detection via shelving, trapping of Rydberg states and high-fidelity single-photon Rydberg excitations.
