(Phys.org)—A team of researchers at Harvard University has successfully cooled a three-atom molecule down to near absolute zero for the first time. In their paper published in Physical Review Letters, ...

A team of researchers at Harvard University, has developed a way to create ultracold polyatomic molecules by trapping and cooling them in three dimensions. In their paper published in the journal ...

Cooling atoms to ultracold temperatures of less than one millikelvin and controlling their internal energy states has led to the development of numerous technologies, including optical atomic clocks 1 ...
