Quantum Simulation

We use reconfigurable arrays of neutral atoms with programmable interactions to study quantum many-body phenomena. In particular we are developing new methods to trap large arrays of atoms (>1000) in arbitrary 2D geometries using optical tweezer arrays. Coherent interactions between the atoms are generated by coupling the atoms to highly excited Rydberg states. With these tools we explore emergent phenomena such as quantum phase transitions, out-of equilibrium dynamics, and topological phases of matter with the ability to control and probe these systems atom-by-atom.
