Researchers use a laser to excite and precisely measure a long-sought exotic nuclear state, paving the way for precise timekeeping and ultrasensitive quantum sensing.
By tweaking the energy of a thorium nucleus with a laser, scientists demonstrated a key step to building clocks based on the physics of atomic nuclei.
Nuclear clocks could allow scientists to probe the fundamental forces of the universe in the future. Researchers have made a crucial advance in this area as part of an international collaboration.
Better clocks could improve technologies that depend on them, such as GPS navigation, and help test fundamental ideas of physics.
