Transformation theory for phase-space representations of quantum mechanics- art. no. 064101

Dirac bras and kets are explicitly defined for phase-space representations of quantum mechanical observables, and simple transformation rules for chan ging representations are constructed. Derivations in the Wigner-Weyl repres entation of an expression for the kernel of the quantum Liouville operator, and of a relation between its stationary and nonstationary eigenstates, de monstrate the power of the resultant algebra.
