Optimal displacement detection of arbitrarily-shaped levitated dielectric objects using optical radiation
Shaun Laing, Shelby Klomp, George Winstone +6
Optically-levitated dielectric objects are promising for precision force, acceleration, torque, and rotation sensing due to their extreme environmental decoupling. While many levit…
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…
Demonstration that Differential Length Changes of Optical Cavities are a Sensitive Probe for Ultralight Dark Matter
Tejas Deshpande, Andra Ionescu, Nicholas Miller +4
Measurements of differential length oscillations of Fabry-Perot cavities provide a sensitive and promising approach to searching for scalar ultralight dark matter (ULDM). The initi…
Simulating the Galactic population of axion clouds around stellar-origin black holes: Gravitational wave signals in the 10-100 kHz band
Jacob R. Sprague, Shane L. Larson, Zhiyuan Wang +6
Ultralight scalar fields can experience runaway `superradiant' amplification near spinning black holes, resulting in a macroscopic `axion cloud' which slowly dissipates via continu…
