Trapping of nanofabricated SiO high-aspect-ratio discs in an optical lattice
Shelby Klomp, Shafaq Gulzar Elahi, Scott Grudichak +13
We describe the nanofabrication and loading of lithographically patterned, high aspect ratio m diameter silicon dioxide discs with thickness of nm into an optical sta…
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 s…
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…
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…
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…
Optomechanics of optically-levitated particles: A tutorial and perspective
George Winstone, Alexey Grinin, Mishkat Bhattacharya +4
Optomechanics, the study of the mechanical interaction of light with matter, has proven to be a fruitful area of research that has yielded many notable achievements, including the…
An apparatus for in-vacuum loading of nanoparticles into an optical trap
Evan Weisman, Chethn Krishna Galla, Cris Montoya +7
We describe the design, construction, and operation of an apparatus utilizing a piezoelectric transducer for in-vacuum loading of nanoparticles into an optical trap for use in levi…
Optical trapping of high-aspect-ratio NaYF hexagonal prisms for kHz-MHz gravitational wave detectors
George Winstone, Zhiyuan Wang, Shelby Klomp +9
We present experimental results on optical trapping of Yb-doped NaYF sub-wavelength-thickness high-aspect-ratio hexagonal prisms with a micron-scale radius. The prisms are trap…
Searching for new physics with a levitated-sensor-based gravitational-wave detector
Nancy Aggarwal, George P. Winstone, Mae Teo +4
The Levitated Sensor Detector (LSD) is a compact resonant gravitational-wave (GW) detector based on optically trapped dielectric particles that is under construction. The LSD sensi…
Static force characterization with Fano anti-resonance in levitated optomechanics
