A first for the Boulder based company: training physicists to create Bose Einstein Condensates in four days. Boulder, Colorado (PRWEB) August 02, 2013 Satyendra Nath Bose and Albert Einstein in 1924 first predicted and described the quantum behavior of atoms when cooled to temperatures very close to Absolute Zero (-273.15C or -459.67F). Advances In laser cooling techniques (for which Claude Cohen-Tannoudji, Stephen Chu and Bill Phillips won a 1997 Nobel Prize) allowed Eric Cornell and...

New Methods For Cooling Of Ions Developed
2012-11-26 15:13:04

Johannes Gutenberg-Universität Mainz Ions are cooled during collisions with cold atoms / Similar processes assumed to occur in space Among the most important techniques developed in atomic physics over the past few years are methods that enable the storage and cooling of atoms and ions at temperatures just above absolute zero. Scientists from Bangalore and Mainz have now demonstrated in an experiment that captured ions can also be cooled through contact with cold atoms...

  Researchers at the Niels Bohr Institute have measured the lifetime of an extremely stable energy level of magnesium atoms with great precision. Magnesium atoms are used in research with ultra-precise atomic clocks. The new measurements show a lifetime of 2050 seconds, which corresponds to approximately ½ hour. This is the longest lifetime ever measured in a laboratory. The results have been published in the scientific journal Physical Review Letters. The experiment...

A research team from the National Institute of Standards and Technology (NIST) and the University of Maryland 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...

Trapping, cooling, and storing neutral atoms requires an elaborate process. As a first method we have, now almost classic, laser cooling in a "magneto-optical trap". Atoms are shot from six directions with laser beams whose frequency lies somewhat below the excitation energy. In this way, the particles always absorb light when they move themselves on the beam - because of the Doppler effect, they are in resonance - and then are slowed down in this direction. We call it cooling, when an...
