Optimisation of table-top 3D interferometers for Observational Quantum Gravity

Autor: Griffiths, William L., Aiello, Lorenzo, Ejlli, Aldo, James, Alasdair L., Vermeulen, Sander M., Dooley, Katherine L., Grote, Hartmut

With the use of twin, co-located, 3D interferometers, Cardiff University's Gravity Exploration Institute aims to observe quantum fluctuations of space-time as predicted by some theories of quantum gravity. Our design displacement sensitivity exceeds

Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nano-meter scale thermo-elastic deformations and substrate lenses from these micron-scale absorbers significantly re

We propose an upgrade to Advanced LIGO (aLIGO), named LIGO-LF, that focuses on improving the sensitivity in the 5-30 Hz low-frequency band, and we explore the upgrade's astrophysical applications. We present a comprehensive study of the detector's te

Status of GEO 600

Autor: Dooley, Katherine L.

The German-British laser-interferometric gravitational wave detector GEO 600 is in its 13th year of operation since its first lock in 2001. After participating in science runs with other first generation detectors, GEO\,600 has continued collecting d
