Kathmandu, March 31 – Scientists have made a groundbreaking advancement by developing an ultra-precise ‘phonon laser’ powered by sound vibrations instead of light. This innovation, created by researchers from the University of Rochester and the Rochester Institute of Technology, promises revolutionary contributions in quantum physics, gravitational studies, and the future development of a ‘quantum compass.’
According to a study published in the Nature Communications journal, Professor Nick Vamivakas and his team successfully managed to control phonons—individual particles of sound—using a laser-like approach. While conventional lasers invented in the 1960s manipulate photons (particles of light), this novel laser controls the mechanical motions or vibrations of materials.
Previously, achieving high precision with such lasers was challenging due to noise interference. However, the scientists employed light assistance to constrain these vibrations and significantly reduce thermal noise. This breakthrough enables gravitational and acceleration measurements with unprecedented accuracy. One of the most notable applications of this technology is its use in navigation systems that operate without satellites—an approach impervious to interference by any method.
