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…
A method for optically trapping nanospheres at micron range from a tilted mirror
Alexey Grinin, Andrew Dana, Mark Nguyen +2
We propose and experimentally demonstrate a novel optical method for trapping and cooling dielectric nanospheres at (sub)-micron distances from a reflective metallic surface. By tr…
Detecting the QCD axion via the ferroaxionic force with piezoelectric materials
Asimina Arvanitaki, Jonathan Engel, Andrew A. Geraci +3
We show that piezoelectric materials can be used to source virtual QCD axions, generating a new axion-mediated force. Spontaneous parity violation within the piezoelectric crystal…
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…
Random acceleration noise on Stern-Gerlach Interferometry in a Harmonic Trap
Sneha Narasimha Moorthy, Andrew Geraci, Sougato Bose +1
We analyze decoherence in a one-loop Stern--Gerlach--type matter-wave interferometer for a massive nanoparticle embedded with a nitrogen vacancy (NV)-centered nanodiamond evolving…
