Webb1 juni 2024 · The applied method, based on the alternation of two successive Ramsey-CPT sequences with unequal free-evolution times and the subsequent management of two interconnected phase and frequency servo loops, is found to allow a relevant reduction of the clock-frequency sensitivity to laser-power variations. Ramsey interferometry, also known as the separated oscillating fields method, is a form of particle interferometry that uses the phenomenon of magnetic resonance to measure transition frequencies of particles. It was developed in 1949 by Norman Ramsey, who built upon the ideas of his mentor, Isidor Isaac Rabi, … Visa mer The Rabi method A simplified version of the Rabi method consists of a beam of atoms, all having the same speed $${\displaystyle v}$$ and the same direction, sent through one interaction zone of … Visa mer Atomic clocks and the SI definition of the second An atomic clock is fundamentally an oscillator whose … Visa mer Early interpretations of atom interferometers, including those of Ramsey, used a classical description of the motion of the … Visa mer WebbRamsey Spectroscopy.
