The Wigner distribution … Nettetof the Wigner function. We encounter similar expressions when we derive the phase space equations de-termining the Moyal function. Therefore, it is useful to first study more general matrix elements and then apply these results to the problem of the quantum Liou-ville equation and the Moyal functions. D.I Formulation of the Problem
The Moyal bracket is a way of describing the commutator of observables in the phase space formulation of quantum mechanics when these observables are described as functions on phase space. It relies on schemes for identifying functions on phase space with quantum observables, the most famous of these schemes being the Wigner–Weyl transform. It underlies Moyal’s dynamical equation, an equivalent formulation of Heisenberg’s quantum equation of motion, ther…
