Nonequilibrium Dynamics in a Three-dimensional Spinor Bose-Hubbard Model Quantum Simulator

Physical modeling of three-dimensional (3D) strongly correlated many-body systems is a fast-moving research frontier with immediate applications spanning from adiabatic quantum state preparations to developing novel materials. We have experimentally demonstrated that the intricate many-body physics can be studied in a 3D spinor Bose-Hubbard model quantum simulator, consisting of lattice-confined spinor Bose-Einstein condensates. Possessing spin degrees of freedom and exhibiting magnetic order and superfluidity, this 3D quantum simulator is highly programmable with an unprecedented degree of control over many parameters. In this talk, I will present a few interesting results realized in the spinor quantum simulator, including nonequilibrium dynamics and the dynamic coupling of spatial and spin degrees of freedom, and discuss their potential applications on quantum-enhanced sensing.
