Optomechanical Accelerometer Search for Ultralight Dark Matter
M. Dey Chowdhury, J. P. Manley, C. A. Condos +2
Cavity optomechanical systems have recently been proposed as detectors for ultralight dark matter, leveraging their ability to cool and probe mechanical oscillators at the quantum…
Fabrication and characterization of high-Q silicon nitride membrane resonators
Atkin D. Hyatt, Oscar A. Flores, Aman R. Agrawal +2
Silicon nitride membranes are a powerful and ubiquitous optomechanical resonator technology, enabling high mechanical Q, low optical loss, and enhanced optomechanical coupling via…
Ultrahigh-Q Torsional Nanomechanics through Bayesian Optimization
Atkin D. Hyatt, Aman R. Agrawal, Christian M. Pluchar +2
Recently it was discovered that torsion modes of strained nanoribbons exhibit dissipation dilution, giving a route to enhanced torque sensing and quantum optomechanics experiments.…
Ultralow loss torsion micropendula for chipscale gravimetry
C. A. Condos, J. R. Pratt, J. Manley +4
We explore a new class of chipscale torsion pendula formed by SiN nanoribbon suspensions. Owing to their unique hierarchy of gravitational, tensile, and elastic stiffness,…
