The repulsive Hubbard Hamiltonian is one of the foundational models describing strongly
correlated electrons and is believed to capture essential aspects of high-temperature …

Strong electron correlations lie at the origin of high-temperature superconductivity. Its
essence is believed to be captured by the Fermi-Hubbard model of repulsively interacting …

In the last decade, quantum simulators, and in particular cold atoms in optical lattices, have
emerged as a valuable tool to study strongly correlated quantum matter. These experiments …

Ultracold atomic gases provide a fantastic platform to implement quantum simulators and
investigate a variety of models initially introduced in condensed matter physics or other …

We report on a detailed experimental investigation of the equation of state (EoS) of the three-
dimensional Fermi-Hubbard model (FHM) in its generalized SU (N)-symmetric form, using a …

We report on the single atom and single site-resolved detection of the total density in a cold
atom realization of the 2D Fermi-Hubbard model. Fluorescence imaging of doublons is …

The complexity of quantum many-body systems originates from the interplay of strong
interactions, quantum statistics, and the large number of quantum-mechanical degrees of …

We report on the site-resolved observation of characteristic states of the two-dimensional
repulsive Fermi-Hubbard model, using ultracold K 40 atoms in an optical lattice. By varying …

The subtle interplay between kinetic energy, interactions, and dimensionality challenges our
comprehension of strongly correlated physics observed, for example, in the solid state. In …

We discuss the density shift and broadening of Rydberg spectra measured in cold, dense
atom clouds in the context of Rydberg atom spectroscopy done at room temperature, dating …
