Nuclear Clock Ticks Towards New Physics Frontier
12 Jun
Summary
- A new nuclear clock uses thorium atoms for highly accurate timekeeping.
- This technology could surpass current atomic clocks in precision.
- It may enable new experiments searching for exotic physics.
A significant advancement in timekeeping has been achieved with the creation of the first functional nuclear clock. This device, developed by researchers at the Vienna University of Technology, leverages the atomic nuclei of radioactive thorium to measure time with unprecedented precision. The project represents the culmination of nearly two decades of dedicated research by scientists like Thorsten Schumm.
Unlike current atomic clocks that rely on electron transitions, this nuclear clock uses the nucleus's higher energy levels. While the prototype's accuracy is still being refined, its stability and ability to operate at room temperature mark it as a revolutionary step. This new technology holds immense potential for advancing fundamental physics research and could even aid in the search for elusive dark matter particles.
