From Quantum Magnetism to Quantum Chemistry -New Avenues for Ultracold Quantum Gases

Recent experiments with quantum gas microscopes allow for an unprecedented view and control of quantum matter in new parameter regimes and with new probes. In our fermionic quantum gas microscope, we can detect both charge and spin degrees of freedom simultaneously, thereby gaining maximum information on the intricate interplay between the two in the paradigmatic Hubbard model. In my talk, I will show how we can reveal hidden magnetic order, directly image individual polarons or probe the fractionalisation of spin and charge in dynamical experiments. For the first time we therefore have access to non-local hidden correlation properties of quantum matter. Furthermore, I will show how quantum gas microscopy can open new avenues for the for field of quantum chemistry when probing and controlling the formation of huge Rydberg macrodimers in optical lattices.
