Levitodynamics: Levitation and control of microscopic objects in vacuum

C Gonzalez-Ballestero, M Aspelmeyer, L Novotny… - Science, 2021‏ - science.org
BACKGROUND Levitation of large objects has become a widely used technique in science
and engineering, and the control of levitated nano-and micro-objects in vacuum has gained …

Massive quantum systems as interfaces of quantum mechanics and gravity

S Bose, I Fuentes, AA Geraci, SM Khan, S Qvarfort… - Reviews of Modern …, 2025‏ - APS
The traditional view from particle physics is that quantum-gravity effects should become
detectable only at extremely high energies and small length scales. Owing to the significant …

Coherent scattering of low mass dark matter from optically trapped sensors

G Afek, D Carney, DC Moore - Physical review letters, 2022‏ - APS
We propose a search for low mass dark matter particles through momentum recoils caused
by their scattering from trapped, nanometer-scale objects. Our projections show that even …

Optical cold dam** of neutral nanoparticles near the ground state in an optical lattice

M Kamba, R Shimizu, K Aikawa - Optics Express, 2022‏ - opg.optica.org
We propose and demonstrate purely optical feedback cooling of neutral nanoparticles in an
optical lattice to an occupation number of 0.85±0.20. The cooling force is derived from the …

Mechanical detection of nuclear decays

J Wang, TW Penny, J Recoaro, B Siegel, YH Tseng… - Physical Review Letters, 2024‏ - APS
We report the detection of individual nuclear α decays through the mechanical recoil of the
entire micron-sized particle in which the decaying nuclei are embedded. Momentum …

Measuring gravity with milligram levitated masses

TM Fuchs, DG Uitenbroek, J Plugge, N van Halteren… - Science …, 2024‏ - science.org
Gravity differs from all other known fundamental forces because it is best described as a
curvature of space-time. For that reason, it remains resistant to unifications with quantum …

Searches for massive neutrinos with mechanical quantum sensors

D Carney, KG Leach, DC Moore - PRX Quantum, 2023‏ - APS
The development of quantum optomechanics now allows mechanical sensors with
femtogram masses to be controlled and measured in the quantum regime. If the mechanical …

Quantum theory of light interaction with a Lorenz-Mie particle: optical detection and three-dimensional ground-state cooling

P Maurer, C Gonzalez-Ballestero, O Romero-Isart - Physical Review A, 2023‏ - APS
We analyze theoretically the motional quantum dynamics of a levitated dielectric sphere
interacting with the quantum electromagnetic field beyond the point-dipole approximation …

Observation and control of Casimir effects in a sphere-plate-sphere system

Z Xu, P Ju, X Gao, K Shen, Z Jacob, T Li - Nature Communications, 2022‏ - nature.com
A remarkable prediction of quantum field theory is that there are quantum electromagnetic
fluctuations (virtual photons) everywhere, which leads to the intriguing Casimir effect. While …

Quantum signatures in nonlinear gravitational waves

T Guerreiro, F Coradeschi, AM Frassino, JR West… - Quantum, 2022‏ - quantum-journal.org
The effective quantum field theory description of gravity, despite its non-renormalizability,
allows for predictions beyond classical general relativity. As we enter the age of gravitational …
