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.

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.

Dynamic relaxation of a levitated nanoparticle from a non-equilibrium steady state
TL;DR: Using a vacuum-trapped nanoparticle, it is demonstrated experimentally the validity of a fluctuation theorem for the relative entropy change occurring during relaxation from a non-equilibrium steady state.

Electromagnetic Diffraction in Optical Systems. I. An Integral Representation of the Image Field
TL;DR: In this article, an integral representation for the electromagnetic field in the image space of an optical system is obtained in the form of an angular spectrum of plane waves, which is closely related to that introduced by Luneberg (1944) as a vector generalization of well-known formulae of Debye (1909) and Picht (1925).

Ultimate limits to inertial mass sensing based upon nanoelectromechanical systems
TL;DR: In this article, the authors evaluate the ultimate mass sensitivity limits for nanomechanical resonators operating in vacuo that are imposed by a number of fundamental physical noise processes, and conclude that these resonators offer immense potential for mass sensing.
