Title: Non-reciprocal interactions and entanglement between optically levitated nanoparticles

Abstract:
Optically levitating dielectric nanoparticles in ultra-high vacuum, where their motion can be cooled into the deep quantum regime, provides a promising platform for force and torque sensing and for high-mass tests of quantum physics. In this talk I will discuss recent results on the coupled dynamics of co-levitated nanoparticles interacting via optical binding and via electrostatic forces. I will show how non-reciprocal interactions [1] and mechanical entanglement [2] between two particles can be generated and observed by controlling the light fields suspending them.
