Innovative Atom Trap Catches Highly Magnetic Atoms (4/3/2008)

Innovative Atom Trap Catches Highly Magnetic AtomsA research team has succeeded in cooling atoms of a rare-earth element, erbium, to within two millionths of a degree of absolute zero using a novel trapping and laser cooling technique. Their recent report* is a major step towards a capability to capture, cool and manipulate individual atoms of erbium, an element with unique optical properties that promises highly sensitive nanoscale force or magnetic sensors, as well as single-photon sources and amplifiers at telecommunications wavelengths. It also may have applications in quantum computing devices. ...> Full Article

The World's Smallest Double Slit Experiment: Breaking up the Hydrogen Molecule (11/12/2007)

The World's Smallest Double Slit Experiment: Breaking up the Hydrogen MoleculeThe big world of classical physics mostly seems sensible: waves are waves and particles are particles, and the moon rises whether anyone watches or not. The tiny quantum world is different: particles are waves (and vice versa), and quantum systems remain in a state of multiple possibilities until they are measured â€" which amounts to an intrusion by an observer from the big world â€" and forced to choose: the exact position or momentum of an electron, say. ...> Full Article
