Event Details & Abstract: 

Quantum simulation is rapidly emerging as a powerful technique to understand the physics of strongly correlated materials. In this talk, I will discuss the development of quantum gas microscopy of ultracold fermionic atoms in an optical lattice to realize the Fermi-Hubbard model, a model widely believed to capture the physics of high-temperature superconductivity. Highlights include: (1) the demonstration of long-range antiferromagnetic order, made possible through a new entropy redistribution technique, (2) the assessment of additional cooling schemes to reach even lower entropies, and (3) the exploration of the interplay between hole motion and spin order through doping an antiferromagnet. I will conclude with an update on our future research directions.
