Sentences with phrase «cooled rubidium»

In breaking this record, Eric Cornell and his colleagues in Boulder cooled rubidium atoms to 5 microkelvin by optical molasses, and then turned off the lasers while keeping the atoms trapped in a magnetic field.

The Boulder researchers have cooled rubidium atoms to just 200 nanokelvin.

The condensate, which is made from around 4000 cooled rubidium atoms, is trapped inside the beams by the same forces used to create optical tweezers, which can manipulate particles on a small scale.

Not exact matches

Cornell and Wieman were trying to cool a puff of rubidium gas to within a few billionths of a degree of absolute zero — colder than any place in nature, even the 2.73 kelvins of space.

The first photon slips into a cloud of rubidium atoms, which were chosen because they can easily be cooled to the extreme point at which they are nearly motionless.

To trap individual neutral atoms, the researchers first used a laser to cool a cloud of rubidium atoms to ultracold, near - absolute - zero temperatures, slowing the atoms down from their usual, high - speed trajectories.

Working out of a lab in WSU's Webster Hall, physicist Peter Engels and his colleagues cooled about one million atoms of rubidium to 100 billionths of a degree above absolute zero.

Using the new approach, which harnesses the quantum interference of matter waves, the team was able to cool a sample of already - cold Rubidium down close to the fundamental temperature limit of laser cooling.

«We catch hundreds of Rubidium atoms in a magnetic trap and cool them so that they form an ultracold Bose - Einstein condensate,» says Professor Jörg Schmiedmayer from the Institute for Atomic and Subatomic Physics at the Vienna University of Technology.

To create these conditions, the team used rubidium atoms that had been cooled down to just above absolute zero using lasers.
