A novel canonical transformation provides insights into many-particle physics

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 leading physics journal Physical Review X on February 12, 2016, Mikhail Lemeshko, Professor at the Institute of Science and Technology Austria (IST Austria), and Richard Schmidt, Postdoc at Harvard University, introduce a technique to understand and calculate angular momentum in settings where
