Part of situation: Development of functional nuclear and atomic clocks (2 clusters)

Nuclear clocks developed by Austrian and Chinese scientists

nuclear clocks thorium-229 quantum physics timekeeping atomic nucleus

Researchers from the Vienna University of Technology and Tsinghua University in Beijing have independently developed the world's first functional nuclear clocks. The findings, published in the journal Nature, mark a significant milestone in timekeeping technology.

Unlike traditional atomic clocks that measure time based on the energy transitions of electrons, nuclear clocks utilize the energy levels of an atom's nucleus. This new method relies on the thorium-229 isotope, which is embedded in calcium fluoride crystals. Because the nucleus is shielded by electrons, these clocks are expected to be more resistant to external electromagnetic and temperature disturbances.

While the current prototypes perform at levels comparable to modern optical atomic clocks, they offer the potential for unprecedented precision. This advancement could eventually enhance GPS navigation, improve communication network security, and provide new tools for investigating fundamental physics, including the search for dark matter.
