Scientists have established a new atomic clock method using superradiant atoms, which promises extraordinary precision in time measurement. In a grandfather clock, these oscillations are from a pendulums swinging from side to side every 2nd, while in an atomic clock, it is a laser beam that corresponds to an energy transition in strontium and oscillates about a million billion times per second.The luminescent ball in the middle called a “magneto-optical trap” (MOT), consists of roughly 300 million strontium atoms suspended in a vacuum chamber cooled to simply above outright no.” Because the atoms constantly need to be changed with fresh brand-new atoms, while brand-new atoms are being prepared, the clock loses time ever so somewhat. We are trying to overcome some of the existing difficulties and limitations of the worlds best atomic clocks by, among other things, recycling the atoms so that they do not require to be changed as frequently,” explains Bohr who was employed at the Niels Bohr Institute when he did the research, but who is now PhD fellow at the University of Colorado.Superradiance and Cooling to Absolute ZeroThe current approach consists of a hot oven that spits roughly 300 million strontium atoms into an extremely cold ball of cold atoms known as a magneto-optical trap, or MOT.
