Bidirectional Internal Squeezing for Gravitational-Wave Detectors
Sander M. Vermeulen, Umran Serra Koca, Lee McCuller
We present a bidirectional internal squeezing scheme for gravitational-wave detectors and show that it saturates the lowest known lower bounds on quantum noise from internal optica…
High-Frequency Thermal Noise in Michelson Interferometers

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 readout for detection and inference of gravitational waves from neutron star merger remnants
Ethan Payne, Lee McCuller, Katerina Chatziioannou
Gravitational waves emitted after neutron star binary coalescences and the information they carry about dense matter are a high-priority target for next-generation detectors. Even…
