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.
David Deutsch David Elieser Deutsch, FRS (born 18 May 1953), is an Israeli-born British physicist at the University of Oxford. He is a Visiting Professor in the Department of Atomic and Laser Physics at the Centre for Quantum Computation (CQC) in the Clarendon Laboratory of the University of Oxford. He pioneered the field of quantum computation by formulating a description for a quantum Turing machine, as well as specifying an algorithm designed to run on a quantum computer. He is a proponent of the many-worlds interpretation of quantum mechanics.
