    Probing antiferromagnetism in the Hubbard model with a quantum gas microscope.

    Probing antiferromagnetism in the Hubbard model with a quantum gas microscope. a, Schematic of the two-dimensional Hubbard phase diagram, including predicted phases. b, Experimental set-up. c, Exemplary raw (left) and processed (right) images of the atomic distribution of single experimental realizations, with both spin components present (upper; corresponding to the starred point in a) and with one spin component removed (lower). The observed chequerboard pattern in the spin-removed images indicates the presence of an antiferromagnet. Credit: (c) Nature (2017). DOI: 10.1038/nature22362
