The recent experiment in the prestigious Massachusetts Institute of Technology has resulted in the world’s coldest molecule. The research was published in Physical Review Letters, a scientific journal. The molecular behavior at lower temperatures will be better understood now. MIT scientists were looking for sodium-potassium gas molecules under critical situations.
The atmosphere around the molecules was cooled down to severally critical temperature of 500 nano kelvins. If we go by standard Fahrenheit scale, this means ultra cool temperature of -459.7 degrees, coldest temperature ever faced by molecules. The research pointed out that the molecules differ in their movements at such low temperature. To achieve this coldest temperature, the researchers used high-tech machines in the laboratory. Cold vapor and Feshbach resonance technique was applied to further cool down the molecule within short span of the time. Physics Professor Martin Zwierlein from MIT informed that this discovery will have important implications in molecular behavior.
He supervised the project. Though the study is only limited to Sodium-potassium gas molecules, the data can be used to predict behavior of other molecules too. The molecules are more stable at lower temperature. At a room temperature, we all know that particles move here and there within small space but condition was not that dynamic at super cold temperature. The researchers say that this information was previously unknown to the scientific world. The immutable condition of the particles has been greatest finding of this experiment. The scientist also observed lower speed of particles during the experiment.
