A neutral-atom Hubbard quantum simulator in the cryogenic regime

Understand

Ultracold fermionic atoms in optical lattices offer pristine realizations of Hubbard models, which are fundamental to modern condensed matter physics.

• Despite significant advancements, the accessible temperatures in these optical lattice material analogs are still too high to address many open problems.
• Here, we demonstrate a several-fold reduction in temperature, bringing large-scale quantum simulations of the Hubbard model into an entirely new regime.
• This is accomplished by transforming a low entropy product state into strongly-correlated states of interest via dynamic control of the model parameters, which is extremely challenging to simulate classically.
