The Jordan formulation of Quantum Mechanics: a review
Paul K. Townsend · arXiv (Cornell University) · 2016
This is a transcription of a conference proceedings from 1985. It reviews the Jordan algebra formulation of quantum mechanics. A possible novelty is the discussion of time evolution; the associator takes over the role of $i$ times the commutator in the standard density matrix formulation, and for the Jordan algebra of complex Hermitian matrices this implies a Hamiltonian of the form $H= i[x,y] + λ\mathbb{I}$ for traceless Hermitian $x,y$ and real number $λ$. Other possibilities for time evolution in the Jordan formulation are briefly considered.
