Dual mass milligram-scale torsion oscillator for vibration-free optomechanical sensing
Jack Manley, Thomas Bsaibes, Charles A. Condos +3
Chip-scale optomechanical devices are driving the miniaturization of inertial sensors and next generation fundamental physics experiments. However, precision at the theoretical lim…
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…
Nanofabricated torsion pendulums for tabletop gravity experiments
Jack Manley, Charles A. Condos, Zachary Fegley +5
Measurement of mutual gravitation on laboratory scales is an outstanding challenge and a prerequisite to probing theories of quantum gravity. A leading technology in tabletop gravi…
Lithographically Defined SiN Torsional Pendulum
Thomas Bsaibes, Charles Condos, Jack Manley +3
Torsion pendulums provide an opportunity to trap large masses in a potential weak enough to explore two-body gravitation. Cooled to, and then released from a ground state, weak qua…
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.…
