JILA’s 3-D Quantum Gas Atomic Clock Offers New Dimensions in Measurement
“JILA physicists have created an entirely new design for an atomic clock, in which strontium atoms are packed into a tiny three-dimensional (3-D) cube at 1,000 times the density of previous one-dimensional (1-D) clocks. In doing so, they are the first to harness the ultra-controlled behavior of a so-called “quantum gas” to make a practical measurement device.”
Jun Ye: Let There Be Light (and Thus, Time)
Dr. Jun Ye, professor of physics at the University of Colorado at Boulder and a fellow of both the National Institute of Standards and Technology and JILA, explains how lasers are used to manipulate atoms inside and out for ultra-precise clocks.
Ultra-Accurate Clocks Lead Search for New Laws of Physics
Atomic clocks are letting physicists tighten the lasso around elusive phenomena such as dark matter.
