Abstract
Optically levitated nanoobjects have been shown to be excellent force or torque sensors. Due to their excellent isolation from the thermal environment, they promise unique sensing applications for fundamental research, such as searching for modifications to gravity or Coulomb’s law or detection of dark matter. In this talk I will show how to greatly enhance the sensing performance with a trap array of optically levitated nanoparticles. I will present increased sensitivity to external noises by exploiting direct coupling mechanisms between particles. Finally, I will discuss how this platform can be used to investigate decoherence due to weak forces.
