TLDR
In this article, a room-temperature motion sensor with record sensitivity was created using a levitating silica nanoparticle and feedback cooling to reduce the noise arising from Brownian motion enables a detector that is perhaps even sensitive enough to detect non-Newtonian gravity-like forces.Abstract:

Cavity cooling a single charged levitated nanosphere.
TL;DR: A new type of hybrid electro-optical trap formed from a Paul trap within a single-mode optical cavity is demonstrated, demonstrating a factor of 100 cavity cooling of 400 nm diameter silica spheres trapped in vacuum and paving the way for ground-state cooling in a smaller, higher finesse cavity.

A User's Guide to Vacuum Technology
TL;DR: In this paper, a user's guide to vacuum technology is presented, along with a discussion of its application in nuclear technology. But this guide is limited to a single application: nuclear power.
Journal ArticleDOI
Optomechanics with levitated particles
TL;DR: Optomechanics is concerned with the use of light to control mechanical objects, and trapped mesoscopic particles are the paradigmatic system for studying nanoscale stochastic processes, and have already demonstrated their utility in state-of-the-art force sensing.
Journal ArticleDOI
Dynamic relaxation of a levitated nanoparticle from a non-equilibrium steady state

Regulation of a microcantilever response by force feedback
TL;DR: In this article, a feedback mechanism is used to control the forces incident on a mechanical microcantilever as a function of the monitored cantilever motion, which is effected by modifying the intensity of an auxiliary laser beam that generates a thermally induced stress.

Short-range force detection using optically-cooled levitated microspheres
TL;DR: It is expected that the proposed system could advance the search for non-Newtonian gravity forces via an enhanced sensitivity of 10(5)-10(7) over current experiments at the 1 μm length scale and may be useful for characterizing other short-range physics such as Casimir forces.
