Exploring doped antiferromagnets with a Quantum Gas Microscope — Petar Bojovic1,2, Sarah Hirthe1,2, Thomas Chalopin1,2, Dominik Bourgund1,2, Si Wang1,2, Timon Hilker1,2, and •Immanuel Bloch1,2,3 — 1Max Planck Institute of Quantum Optics — 2Munich Center for Quantum Science and Technology — 3Ludwig Maximilian University
We use our quantum gas microscope of fermionic 6Li atoms loaded into the optical lattices to realize and study magnetic phases of the Fermi-Hubbard model with single-site spin and density resolution. In this talk, I will present our recent implementation of highly stable and tunable optical bichromatic superlattices, which provide the flexibility to test promising cooling protocol and reach novel phases of matter. I will furthermore discuss how we use a digital micromirror device (DMD) for potential shaping on individual sites and create tailored geometries [1, 2]. In such microscopically engineered systems, we can investigate interaction mechanisms in hole- or doublon- doped antiferromagnets and probe the formation of magnetically induced bound pairs among dopants.
