Observation of Spatial Charge and Spin Correlations in the 2D Fermi-Hubbard Model
Lawrence W. Cheuk, Matthew A. Nichols, Katherine R. Lawrence +7
Strong electron correlations lie at the origin of transformative phenomena such as colossal magneto-resistance and high-temperature superconductivity. Already near room temperature…

Observation of 2D fermionic Mott insulators of K with single-site resolution
Lawrence W. Cheuk, Matthew A. Nichols, Katherine R. Lawrence +3
We report on the site-resolved observation of characteristic states of the two-dimensional repulsive Fermi-Hubbard model, using ultracold K atoms in an optical lattice. By v…
