LOCAL KINETIC-ENERGY IN QUANTUM-MECHANICS

The question of local kinetic energy in quantum mechanics is considered by using the phase space formulation of quantum mechanics. We derive the totality of possible quantum mechanical expressions for local kinetic energy and give a subset which satisfy Bader's criterion. The different definitions that various authors have used are shown to be directly related to particular quasiprobability distributions and correspondence rules. © 1979 American Institute of Physics.
