Who introduced a map that was used by a Nobel Prize winning physicist to work out the theory of quantum angular momentum?
Jordan map In theoretical physics, the Jordan map, often also called the Jordan–Schwinger map is a map from matrices M to bilinear expressions of quantum oscillators which expedites computation of representations of Lie Algebras occurring in physics. It was introduced by Pascual Jordan in 1935 and was utilized by Julian Schwinger in 1952 to re-work out the theory of quantum angular momentum efficiently, given that map’s ease of organizing the (symmetric) representations of su(2) in Fock space.
Philip Morrison Philip Morrison (November 7, 1915 – April 22, 2005) was a professor of physics at the Massachusetts Institute of Technology (MIT). He is known for his work on the Manhattan Project during World War II, and for his later work in quantum physics, nuclear physics and high energy astrophysics.
