Simulating Non-equilibrium Dynamics of XX/XXZ/XYZ Spin Chains with Molecular Tweezer Arrays

Programmable molecular tweezer arrays are a new platform for quantum science, with recent work demonstrating the essential building blocks for quantum simulation and quantum information processing. In this talk, I will report work on simulating many-body quantum spin chains using tweezer arrays of CaF molecules. Specifically, leveraging their intrinsic dipolar interactions and using Floquet engineering techniques, we realize tunable 1/r^3 XX/XXZ/XYZ quantum spin models. I will discuss several observations including coherent quantum dynamics of single spin excitations, repulsive magnon bound states, and pair creation/annihilation dynamics. Our work constitutes the first use of molecular tweezer arrays for many-body quantum simulation, enabling further explorations on quantum spin models such as study of magnetic phases and transport behavior.
