A new method of trapping and cooling atoms has been realized by a team of CAIQuE researchers in Wes Campbell's group at UCLA. Andrew Jayich, Xueping Long, and Campbell used a pulsed laser known as a frequency comb to cool 10 million rubidium atoms to about 60 microkelvin. The team has developed a theoretical model that demonstrates that the method can also be used to cool species important to biology and astronomy such as atomic hydrogen, antihydrogen, carbon, oxygen and nitrogen.
