Error signals for overcoming the laser power limits of gravitational-wave detectors
Liu Tao, Pooyan Goodarzi, Jonathan W. Richardson
A major barrier to improving the quantum-limited sensitivity of gravitational-wave observatories is the thermal distortions of the test masses which arise at megawatt laser power.…
Demonstration of a next-generation wavefront actuator for gravitational-wave detection
Tyler Rosauer, Huy Tuong Cao, Mohak Bhattacharya +11
In the last decade, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European Virgo observatory have opened a new observational window on the universe. These…
Expanding the Quantum-Limited Gravitational-Wave Detection Horizon
Liu Tao, Mohak Bhattacharya, Peter Carney +9
We demonstrate the potential of new adaptive optical technology to expand the detection horizon of gravitational-wave observatories. Achieving greater quantum-noise-limited sensiti…
Multivariate Time Series Clustering for Environmental State Characterization of Ground-Based Gravitational-Wave Detectors
Rutuja Gurav, Isaac Kelly, Pooyan Goodarzi +4
Gravitational-wave observatories like LIGO are large-scale, terrestrial instruments housed in infrastructure that spans a multi-kilometer geographic area and which must be actively…
Squeezing the quantum noise of a gravitational-wave detector below the standard quantum limit
Wenxuan Jia, Victoria Xu, Kevin Kuns +168
Precision measurements of space and time, like those made by the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO), are often confronted with fundamental…
