Sentences with word «microkelvin»

The team managed to get their SrF molecules chilled to around 300 microkelvin in one direction.

In the late 1980s laser specialists refined the technique to cool atoms down to several microkelvin.

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.

Helium atoms have been cooled to two microkelvins along one dimension, and work is under way to extend this technique to two and three dimensions.

The atoms are cooled with lasers and trapped with magnetic fields at very cold, microkelvin temperatures.

To trap the atoms in optical tubes, scientists first use blue and red lasers to cool strontium atoms to about 2 microKelvin in a trap that uses light and magnetic fields.

This slowed down the caesium atoms, cooling them to 1.2 microkelvin.

Below one microkelvin, however, atoms drift at a leisurely rate of half a centimetre per second.

When the team subtracted the dipole pattern, they found «ripples» — residual temperature variations of 0.011 per cent (30 5 microkelvin)-- dotted around the sky in regions away from the Galaxy.

For cesium atoms, it means a temperature lower than three microkelvins.

Edward Shuman, John Barry and David DeMille, all from Yale University in New Haven, Conn., used an old technique and several new tricks to cool molecules of strontium monofluoride (SrF) to just a few hundred microkelvin.

The strontium atoms in each standard are isolated from the environment and from one another: cooled to a temperature below 10 microkelvins, they are situated inside an ultrahigh vacuum chamber and immobilized in a specially constructed optical trap generated by the beam of a supplementary laser.

The team cooled the gas to around 1 microkelvin, and then handed control of the three laser beams over to the artificial intelligence to cool the trapped gas down to nanokelvin.
