Am Montag (24.10.22) um 12.00 Uhr c.t. findet der nächste Termin unseres Physikalischen Kolloquiums statt.
Referentin ist Prof. Dr. Michèle Heurs (AEI Hannover) zum Thema: „Gravitational Waves in a New Light“.
Since the first direct detection of gravitational waves in 2015, we have gained an entirely new observation window to the universe – now, we not only have electromagnetic telescopes and neutrino detectors to view astrophysical events, but we can also listen to the cosmos using interferometric gravitational wave detectors. The sensitivity of these interferometers is so incredible that quantum effects of the employed light have already become limiting. Ultra-precisely stabilised lasers do not suffice; non-classical (fixed-quadrature squeezed) light is already routinely employed in the current (second) generation gravitational wave detectors (such as aLIGO and AdVirgo).To achieve ever-higher detection rates for meaningful gravitational wave astronomy, ever-greater detection sensitivity is required. In this talk, I will introduce the principle of interferometric gravitational wave detection and highlight some of the advanced technologies employed in Advanced LIGO. I will conclude my talk by showing some recent results and further possibilities, as well as options for quantum noise reduction in laser interferometry and the broader field of quantum optics.
