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:

Nonclassical states of levitated macroscopic objects beyond the ground state
TL;DR: In this article, the possibility of conditional squeezing of a levitated particle induced by the homodyne detection of light in a pulsed optomechanical setup within the resolved sideband regime was analyzed.
Journal ArticleDOI
Quantum hypergraph states in continuous variables
TL;DR: This work defines a new non-Gaussian class of states based on hypergraphs which satisfy the requirements of the Lloyd-Braunstein criteria while restricted to a Gaussian measurement strategy.

Spectral analysis and parameter estimation in levitated optomechanics
Chris Dawson,James Bateman +1 more
TL;DR: In this article, the authors present an apparatus optimized for sensitivity along one motional degree of freedom, a theoretical model of the spectrum, and maximum likelihood estimation, which accounts for the sinusoidal dependence of interferometric signal on particle position.

Single Particle Thermodynamics with Levitated Nanoparticles
James Millen,Jan Gieseler +1 more
TL;DR: In this article, the authors review the application of levitated nanoparticles as a new experimental platform to explore stochastic thermodynamics in small systems and propose a method to explore quantum physics in the regime where the particle dynamics are purely classical.

Direct measurement of optical trapping force gradient on polystyrene microspheres using a carbon nanotube mechanical resonator.
TL;DR: This study demonstrates direct measurement of the optical force gradient distribution acting on a polystyrene (PS) microsphere using a carbon nanotube (CNT) mechanical resonator, where a PS microspheres with 3 μm diameter is welded at the CNT tip using laser heating.

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.
Journal Article
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.
