String Patterns in the Doped Hubbard Model

Abstract

Quantum simulation is rapidly emerging as a powerful technique to understand the physics of strongly correlated materials. Quantum gas microscopy of ultracold fermionic atoms in an optical lattice is perfectly suited to study the Fermi-Hubbard model, a model widely believed to capture the physics of high-temperature superconductivity. We realize a Fermi-Hubbard antiferromagnet and investigate the interplay between hole motion and spin order through doping the antiferromagnet. In addition to using conventional observables such as the spin correlation function and the staggered magnetization, we explore the potential for new pattern-based microscopic observables for quantum simulation of strongly correlated materials.
