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:

Thermally induced micro-motion by inflection in optical potential.
TL;DR: An experimental set-up of holographic optical tweezers is exploited to experimentally investigate Brownian motion of a micro-particle near the inflection point of the cubic optical potential to evaluate specific statistical moment ratios demonstrating strongly non-linear stochastic dynamics.

Comprehensive study on the nonlinear optical properties of few-layered MoSe2 nanosheets at 1 μm
TL;DR: In this article, a few-layered molybdenum diselenide (MoSe2) nanosheets were synthesized by the simple and low-cost ultrasonic-assisted liquid phase exfoliation (UALPE) method.

Radiative heat transfer in nonlinear Kerr media
TL;DR: In this paper, the authors obtained a fluctuation-dissipation theorem describing thermal electromagnetic fluctuation effects in nonlinear media that they exploited in conjunction with a stochastic Langevin framework to study thermal radiation from photonic cavities coupled to external environments at and out of equilibrium.
Journal ArticleDOI
Thermal radiation from optically driven Kerr ($\chi^{(3)}$) photonic cavities
TL;DR: In this article, thermal radiation from nonlinear photonic cavities coupled to external channels and subject to incident monochromatic light was studied and it was shown that bistability can enhance thermal radiation by orders of magnitude and result in strong lineshape alternations, including super-narrow spectral peaks occurring at the onset of kinetic phase transitions.

Single spin detection by magnetic resonance force microscopy
TL;DR: The long relaxation time of the measured signal suggests that the state of an individual spin can be monitored for extended periods of time, even while subjected to a complex set of manipulations that are part of the MRFM measurement protocol.

Zeptogram-Scale Nanomechanical Mass Sensing
TL;DR: Analysis of the ultimate sensitivity of very high frequency nanoelectromechanical systems indicates that NEMS can ultimately provide inertial mass sensing of individual intact, electrically neutral macromolecules with single-Dalton (1 amu) resolution.

A nanomechanical mass sensor with yoctogram resolution
TL;DR: This unprecedented level of sensitivity allows us to detect adsorption events of naphthalene molecules, and to measure the binding energy of a xenon atom on the nanotube surface, which could have applications in mass spectrometry, magnetometry and surface science.

On the Resistance Experienced by Spheres in their Motion through Gases
TL;DR: In this article, the authors derived the force exerted by the impinging molecules leaving the surface depending on how they leave, assuming the usual Maxwellian distribution of velocities in the gas, the force was found to be M where M=(4π/3) Nma2cmV, N, m, a, and V being the number per unit volume, mass, radius, and mean speed of the molecules and V the speed of a droplet.
