Localized efficient in-vacuum loading of 0.1-10 m spherical and plate-like particles into optical traps using a pulled glass capillary
Alexey Grinin, Andrew Dana, Mark Nguyen +8
We demonstrate a compact piezoelectric-driven micropipette launcher for localized in-vacuum delivery of nano- and microparticles into optical traps. The launcher has been integrate…
Gravitational wave signal and noise response of an optically levitated sensor in a Fabry-Pérot cavity
Andrew Laeuger, Shafaq Gulzar Elahi, Shelby Klomp +8
Optically levitated sensors inside a Fabry-Pérot cavity have been proposed for high-frequency gravitational-wave (GW) detection, though their configuration for gravitational wave…
An Optomechanical Coin Flip: Wavelength-Modulated, Erbium-Powered Rotations in a Levitated System
George Winstone, Maddox Wroblewski, Lars Forberger +9
Optical levitation of nano-scale systems offers a pathway to highly sensitive rotation measurements, which are critical for advancing gyroscopic technologies. While prior studies h…
Magnetic levitation and spatial superposition of a nanodiamond with a current-carrying chip
Qian Xiang, Shafaq Gulzar Elahi, Andrew Geraci +2
We propose a current-carrying-chip scheme for generating spatial quantum superpositions using a levitating nanodiamond with a built-in nitrogen-vacancy (NV) centre defect. Our setu…
Diamagnetic microchip traps for levitated nanoparticle entanglement experiments
Shafaq Gulzar Elahi, Martine Schut, Andrew Dana +4
The Quantum Gravity Mediated Entanglement (QGEM) protocol offers a novel method to probe the quantumness of gravitational interactions at non-relativistic scales. This protocol lev…
