The remarkable discovery of “universality” in Bose-Einstein condensates of atoms has been made by physicists at the University of Queensland. It has been found that the interactions between these gases can be described by a universal law, the so-called “Feynman-Tan” interaction. This law states that two particles interact with a universal strength proportional to the square of their distance. This discovery could have a significant impact on our understanding of the behavior of Bose-Einstein condensates, and it may open up new possibilities for controlling and manipulating these gases.
