AWhat changed
Truppe and colleagues trapped calcium monofluoride molecules, then switched the trap field off and applied three-dimensional optical molasses. Expansion images gave a temperature of 52 ± 2 microkelvin for the stated measurement, below the relevant Doppler limit. The work improved access to colder molecular samples.
Scientific scope
Truppe and colleagues trapped calcium monofluoride molecules, then switched the trap field off and applied three-dimensional optical molasses. Expansion images gave a temperature of 52 ± 2 microkelvin for the stated measurement, below the relevant Doppler limit. The work improved access to colder molecular samples. The quoted temperature was obtained in the later molasses stage, not inside the initial magneto-optical trap. The result relies on imaging and expansion analysis; it did not establish a quantum-degenerate gas or demonstrate the later applications proposed in the paper.
