Vacuum forces between nanoparticles

07 May 2024

In this work, we apply the tools of macroscopic quantum electrodynamics to calculate the interaction between two optically levitated nanoparticles. We recover the optical binding forces, as well as the Casimir-Polder interaction. Furthermore, we investigate how a squeezed vacuum state of light can also result in optical interactions between two nanoparticles.
