Description
Light is regularly used to trap polarizable objects, such as atoms, molecules, or dielectric nanoparticles. Light is also scattered from them, inducing an interaction mechanism known as light-induced dipolar forces (optical binding). This interaction enables quantum control of the collective motion of arrays of objects, leading to novel opportunities for quantum sensing, quantum metrology, and quantum information science.
In my talk, I will discuss two aspects of cooperative phenomena that arise from tunable light scattering in tweezer arrays of silica nanoparticles. I will show how we can use Floquet-driven, nonreciprocal optical interactions to realize quantum operations on the motion of two trapped objects. Finally, I will present our results on arranging arrays of objects to engineer collective light scattering.
