@inproceedings{Yang2021SiteResolvedIO, title={Site-Resolved Imaging of Ultracold Fermions in a Triangular-Lattice Quantum Gas Microscope}, author={Jin Yang and Liyu Liu and Jirayu Mongkolkiattichai and Peter Schauss}, year={2021} }

Quantum gas microscopes have expanded the capabilities of quantum simulation of Hubbard models by enabling the study of spatial spin and density correlations in square lattices. However, quantum gas microscopes have not been realized for fermionic atoms in frustrated geometries. Here, we demonstrate the single-atom resolved imaging of ultracold fermionic Li atoms in a triangular optical lattice with a lattice constant of 1003 nm. The optical lattice is formed by a recycled narrow-linewidth…
