Get Ready For Nuclear Clocks

Long-time Slashdot reader jrronimo says JILA physicist Jun Ye's group "has made a breakthrough towards the next stage of precision timekeeping." From their paper recently published to arXiv:Optical atomic clocks use electronic energy levels to precisely keep track of time. A clock based on nuclear energy levels promises a next-generation platform for precision metrology and fundamental physics studies.... These results mark the start of nuclear-based solid-state optical clocks and demonstrate the first comparison of nuclear and atomic clocks for fundamental physics studies. This work represents a confluence of precision metrology, ultrafast strong field physics, nuclear physics, and fundamental physics.
