Abstract
A system includes a vacuum chamber to receive a laser beam and a charged nanoparticle. The nanoparticle oscillates at a trapping frequency in a focus of the laser beam. Resonant oscillation of the nanoparticle is driven by a presence of an ambient electric field adjacent to the vacuum chamber. The system also includes a controller to tune the trapping frequency of an oscillating nanoparticle to be in resonance with the ambient electric field causing on-resonant enhancement of the system; a detector to detect positional changes of the oscillating nanoparticle; and a processor to calculate an electromagnetic force of the ambient electric field based on the positional changes of the oscillating nanoparticle.
