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:

A proposal for the experimental detection of CSL induced random walk.
TL;DR: In this article, it was shown that the CSL effect can be seen at the pressure of about a pico-Torr, where Torr is defined as the minimum pressure required by the Schrodinger equation.
Journal ArticleDOI
Non-equilibrium steady state of a driven levitated particle with feedback cooling
TL;DR: In this article, the authors derived an analytical expression for the energy distribution of this steady state showing that the average and variance of energy distribution can be controlled separately by appropriate choice of the friction, cooling and modulation parameters.

Thermal radiation from optically driven Kerr (χ(3)) photonic cavities
TL;DR: In this article, thermal radiation from nonlinear (χ(3)) photonic cavities coupled to external channels and subject to incident monochromatic light is described, showing that bistability can enhance thermal radiation by orders of magnitude and result in strong lineshape alternations.

Nonlinear Nanomechanical Mass Spectrometry at the Single-Nanoparticle Level
TL;DR: A measurement architecture with which to operate at the nonlinear regime and measure frequency shifts induced by analytes in a rapid and sensitive manner is developed and can be used for thin nanomechanical structures that possess a limited dynamic range.

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.

Single spin detection by magnetic resonance force microscopy
TL;DR: In this article, the authors reported the detection of an individual electron spin by magnetic resonance force microscopy (MRFM) and achieved a spatial resolution of 25nm in one dimension for an unpaired spin in silicon dioxide.

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.
Journal ArticleDOI
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.
