Sentences with phrase «ultracold molecules»

Zwierlein's group chose to create ultracold molecules of sodium potassium, as this molecule is chemically stable and naturally resilient against reactive molecular collisions.

They then essentially glued the atoms together to form ultracold molecules, applying a magnetic field to prompt the atoms to bond — a mechanism known as a «Feshbach resonance,» named after the late MIT physicist Herman Feshbach.

The researchers found that the ultracold molecules were relatively long - lived and stable, resisting reactive collisions with other molecules.

Zwierlein's group sought to create ultracold molecules of sodium potassium, each consisting of a single sodium and potassium atom.

JILA scientists first created ultracold molecules in 2008 and several years ago formed the first molecular crystal, in which the molecules swapped spins.

Physicists at JILA have made their «quantum crystal» of ultracold molecules more valuable than ever by packing about five times more molecules into it.

That way the team has produced the largest ensemble of ultracold molecules ever and has thus set a new record.

Not exact matches

To create the molecules, JILA's Cornell and Peter Engels and Maren Mossman of Washington State University in Pullman will apply a magnetic field to ultracold atoms of potassium - 39.

In their earlier work, the Colorado group observed a significant drawback of their ultracold potassium rubidium molecules: They were chemically reactive, and essentially came apart when they collided with other molecules.

Here we prepare an ultracold few - body quantum state of reactants and demonstrate state - to - state chemistry for the recombination of three spin - polarized ultracold rubidium (Rb) atoms to form a weakly bound Rb2 molecule.

She and fellow U.C.B. physicist Jun Ye recently succeeded in making a gas of ultracold polar molecules of potassium and rubidium near the temperature of the quantum regime where Jin previously observed a fermionic condensate.
