High-Frequency Thermal Noise in Michelson Interferometers
Daniel Grass, Sander M. Vermeulen, Ian A. O. MacMillan +1
Thermal noise in optics constrains the precision of optical experiments, including Michelson interferometers, optical clocks, and optomechanical sensors. While high-power optical e…

Robust Bilinear-Noise-Optimal Control for Gravitational-Wave Detectors: A Mixed LQG/ Approach
Ian A. O. MacMillan, Lee P. McCuller
At its lowest frequencies, LIGO is limited by noise in its many degrees of freedom of suspended optics, which, in turn, introduce noise in the interferometer through their feedback…

Photon Counting Interferometry to Detect Geontropic Space-Time Fluctuations with GQuEST
Sander M. Vermeulen, Torrey Cullen, Daniel Grass +8
The GQuEST (Gravity from the Quantum Entanglement of Space-Time) experiment uses tabletop-scale Michelson laser interferometers to probe for fluctuations in space-time. We present…
