Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of such ...
Researchers from the University of Southampton have demonstrated for the first time a new laser cooling method, based upon the interference of matter waves, that could be used to cool molecules.

Researchers at the Harvard-MIT Center for Ultracold Atoms have recently demonstrated a one-dimensional (1-D) magneto-optical trap (MOT) of polar free radical calcium monohydroxide (CaOH). This technique, outlined in a paper ...
Scientists using James Webb Space Telescope just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, Webb confirmed a physical process involving the drifting ...
