The concepts of rotation and angular momentum play a crucial role in many areas of physics,ranging from nuclear spectroscopy to molecular collisions and precision measurements. In a paper appearing in the main physics journal Physical Review X on February 12, 2016, and Mikhail Lemeshko,Professor at the Institute of Science and Technology Austria (IST Austria), and Richard Schmidt, or Postdoc at Harvard University,introduce a technique to understand and calculate angular momentum in settings where many particles interact with each other, so-called many-particle systems.
