New Accuracy Record for Molecular Lattice Clock

Charles Day

Researchers have attained a 100-fold increase in the accuracy of a molecular clock that could serve as a terahertz-frequency standard and as a platform for investigating new physics.By Charles Day M olecules can rotate, vibrate, and twist.With each of those degrees of freedom comes a ladder of quantized energy levels whose spacings typically occupy the terahertz band.Because the ladder's steps are tiny, molecules are exquisitely sensitive probes of internal and external fields.But the sensitivity complicates the two principal operations needed to build a working probe: cooling and trapping.In 2019 Tanya Zelevinsky of Columbia University and her collaborators overcame those hurdles to measure a vibrational transition in diatomic strontium to one part in 10 12 .Now, after four years of improvements to the experiment, the team has attained an accuracy 100 times greater [1].Zelevinsky and her team chose Sr 2 for their molecular clock Running a molecular lattice clock requires multiple lasers, mirrors, prisms, and other optical components.Researchers have attained a 100-fold increase in the accuracy of a molecular clock that could serve as a terahertz-frequency standard and as a platform for investigating new physics.By Charles Day M olecules can rotate, vibrate, and twist.With each of those degrees of freedom comes a ladder of quantized energy levels whose spacings typically occupy the terahertz band.Because the ladder's steps are tiny, molecules are exquisitely sensitive probes of internal and external fields.But the sensitivity complicates the two principal operations needed to build a working probe: cooling and trapping.In 2019 Tanya Zelevinsky of Columbia University and her collaborators overcame those hurdles to measure a vibrational transition in diatomic strontium to one part in 10 12 .Now, after four years of improvements to the experiment, the team has attained an accuracy 100 times greater [1].Zelevinsky and her team chose Sr 2 for their molecular clock Running a molecular lattice clock requires multiple lasers, mirrors, prisms, and other optical components.
