Keeping time with an atomic nucleus

25 May 2023

Nuclear clocks could allow scientists to probe the fundamental forces of the universe in the future. LMU researchers have made a crucial advance in this area as part of an international collaboration.

Atomic clocks measure time so precisely that they gain or lose less than a second every 30 billion years. With so-called nuclear clocks, it would be possible to measure time even more accurately. Furthermore, they would enable scientists to delve deeper into fundamental physical phenomena. “We’re talking about the forces that hold the world together at its core,” says LMU physicist Professor Peter Thirolf, who has been researching nuclear clocks for many years.
