Optical lattice quantum materials: A quantum playground

October 7, 2019 - 11:00am
Markus Greiner

With quantum simulations it becomes possible to explore many-body quantum physics in regimes that are beyond what is computationally accessible. Using ultracold fermionic atoms in optical lattices, we realize the iconic “Fermi-Hubbard” model, and our quantum gas microscope gives us ultimate single particle control. We have observed antiferromagnetism in the Hubbard model and signatures of geometric strings upon doping; now we are starting to "zoom in" on the low-temperature phases of this model, which may hold the key to understanding quantum materials such as high temperature superconductors and beyond.
