Washington: Researchers from the University of the West of Scotland (UWS) have made a discovery that has opened up new research avenues in the study of the universe and gravitational waves.
The ground-breaking advancement in thin-film technology aims to increase the sensitivity of gravitational wave detectors both now and in the future. The breakthrough, created by researchers at UWS's Institute of Thin Films, Sensors and Imaging (ITFSI), may help us better comprehend how the cosmos works.
Gravitational waves, first predicted by Albert Einstein's theory of general relativity, are ripples in the fabric of spacetime caused by the most energetic events in the cosmos, such as black hole mergers and neutron star collisions. Detecting and studying these waves provides invaluable insights into the fundamental nature of the universe.
Dr Carlos Garcia Nunez, a senior lecturer at School of Computing, Engineering and Physical Sciences (CEPS), said: "At the Institute of Thin Films, Sensors and Imaging, we are working hard to push the limits of thin film materials, exploring new techniques to deposit them, controlling their properties in order to match the requirements of current and future sensing technology for the detection of gravitational waves."
"The development of high reflecting mirrors with low thermal noise opens a wide range of applications, which covers from the detection of gravitational waves from cosmological events to the development of quantum computers," he added.
The technique used in this work -- originally developed and patented by Professor Des Gibson, Director of UWS's Institute of Thin Films, Sensors and Imaging - could enable the production of thin films that achieve low levels of "thermal noise". The reduction of this kind of noise in mirror coatings is essential to increase the sensitivity of current gravitational wave detectors - allowing the detection of a wider range of cosmological events - and could be deployed to enhance other high-precision devices, such as atomic clocks or quantum computers.
Professor Gibson said, "We are thrilled to unveil this cutting-edge thin film technology for gravitational wave detection. This breakthrough represents a significant step forward in our ability to explore the universe and unlock its secrets through the study of gravitational waves. We believe this advancement will accelerate scientific progress in this field and open up new avenues for discovery."
"UWS's thin film technology has already undergone extensive testing and validation in collaboration with renowned scientists and research institutions. The results have been met with great enthusiasm, fuelling anticipation for its future impact on the field of gravitational wave astronomy. The coating deposition technology is being commercialised by UWS spinout company, Albasense Ltd," Professor Gibson added.
The development of coatings with low thermal noise will not only make the future generations of gravitational wave detectors more precise and sensitive to cosmic events but will also provide new solutions to atomic clocks and quantum mechanics, both highly relevant for the United Nations' Sustainable Development Goals 7, 9 and 11. —ANI
