JILA 3-D Quantum Gas Atomic Clock New Dimensions Measurement
2017/10/25
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-dimensi...
Expansion of a Quantum Gas Released from an Optical Lattice
Ultracold atoms optical lattice quantum gas the diffraction optics
2014/12/19
We analyze the interference pattern produced by ultracold atoms released from an optical lattice, commonly interpreted as the momentum distributions of the trapped quantum gas. We show that for finite...
