Quantum-classical correspondence using projection operators
Copyright policy )Quantum-classical correspondence using projection operators
Classical properties, associated with a large phase space domain with a smooth boundary as compared to the Planck constant, are shown to be expressed quantum-mechanically by a family of quantum projection operators with the help of known theorems in microlocal analysis. Under the conditions of Egorov’s theorem, the conservation of this correspondence under classical/quantum dynamics is asserted.
