A Spaceborne Mounting Method for Fixing a Cubic Fabry–Pérot Cavity in Ultra-Stable Lasers
Applied Sciences, 2022 A spaceborne mounting method for fixing a 100 × 100 × 100 mm cubic Fabry–Pérot (FP) cavity is presented. The method constrains the FP cavity in eight directions with a titanium bracket, PEEK gaskets, and vacuum glue.

Twisted gravitational waves [PDF]
Physical Review D, 2018 In general relativity (GR), linearized gravitational waves propagating in empty Minkowski spacetime along a fixed spatial direction have the property that the wave front is the Euclidean plane. Beyond the linear regime, exact plane waves in GR have been studied theoretically for a long time and many exact vacuum solutions of the gravitational field ...

Did Goryachev et al. detect megahertz gravitational waves? [PDF]
Physical Review D 104, 103017 (2021), 2021 Goryachev et al. [1] recently announced the detection of "two strongly significant events" in their Bulk Acoustic Wave High Frequency Gravitational Wave Antenna. They claim many possibilities for the cause of these events, including high-frequency megahertz gravitational waves.

Probing supermassive black hole binaries with orbital resonances of laser-ranged satellites
European Physical Journal C: Particles and Fields, 2023 Coalescing supermassive black hole binaries (SMBHBs) are the primary source candidates for low frequency gravitational wave (GW) detections, which could bring us deep insights into galaxy evolutions over cosmic time and violent processes of spacetime ...

Drop breakage in a single‐pass through vortex‐based cavitation device: Experiments and modeling
AIChE Journal, Volume 69, Issue 1, January 2023., 2023 Abstract Liquid–liquid emulsions are used in many sectors such as personal care, home care, and food products. There is an increasing need for developing compact and modular devices for producing emulsions with desired droplet size distribution (DSD). In this work, we have experimentally and computationally investigated an application of vortex‐based ...

Pseudoplane-wave gravitational calibrator for gravitational wave observatories
Physical Review D, 2023 The precisions of existing gravitational calibrators for gravitational wave observatories are limited by their dependence on the relative position between the calibrators and the observatory's test masses. Here we present a novel geometry consisting of four quadrupole rotors placed at the vertices of a rectangle centered on the test mass.
