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
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…
Bayesian frequency estimation at the fundamental quantum limit
James W. Gardner, Tuvia Gefen, Ethan Payne +6
Searching for a weak signal at an unknown frequency is a canonical task in experiments probing fundamental physics such as gravitational-wave observatories and ultra-light dark mat…
Signatures of Correlation of Spacetime Fluctuations in Laser Interferometers
B. Sharmila, Sander M. Vermeulen, Animesh Datta
Spacetime fluctuations (SFs), a common feature of different proposed gravity models, could be detected using laser interferometers. In the search for SFs, a correspondence between…
Broadband limits on stochastic length fluctuations from a pair of table-top interferometers
Abhinav Patra, Lorenzo Aiello, Aldo Ejlli +10
The Quantum-Enhanced Space-Time (QUEST) experiment consists of a pair of co-located Power Recycled Michelson Interferometers, each designed to have a broadband, shot-noise limited…
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…
Searching for scalar field dark matter with LIGO
Alexandre S. Göttel, Aldo Ejlli, Kanioar Karan +4
We report on a direct search for scalar field dark matter using data from LIGO's third observing run. We analyse the coupling of size oscillations of the interferometer's beamsplit…
Imprints of massive black-hole binaries on neighbouring decihertz gravitational-wave sources
Jakob Stegmann, Lorenz Zwick, Sander M. Vermeulen +2
The most massive black holes in our Universe form binaries at the centre of merging galaxies. The recent evidence for a gravitational-wave (GW) background from pulsar timing may co…
