NettetIt is true that it was widely felt that classical mechanics is a limit, for h -~ 0, of quantum mechanics. But this could be made somewhat explicit only by the introduction of the Moyal-Vey products and brackets [ 14] and completely rigorous only by the autonomous formulation [3] of quantum mechanics on phase-space.

Nettet"Further, by emphasising the constancy of h-bar in the relation [change of]X times [change of]P approximates h-bar one tends to be led to the notion that the... NettetMoyal bracket description is motivated by the fact that the matrix theory takes on an aspect analogous to a Moyal formulation of quantum mechanics [4]. Note by the way, that the Moyal bracket is defined via the star product known to be an essential ingredient towards setting a non commutative geometry framework [5-6].

Nettete. In physics, Liouville's theorem, named after the French mathematician Joseph Liouville, is a key theorem in classical statistical and Hamiltonian mechanics. It asserts that the phase-space distribution function is constant along the trajectories of the system —that is that the density of system points in the vicinity of a given system ... Nettet13. mar. 2024 · To first order in the time step \varepsilon = -i \Delta t/\hbar, the Moyal bracket [ 4, 8] of quantum phase space dynamics agrees with the classical Poisson bracket [ 6, 8 ]. We therefore have to hope that the commutator [\hat { {\varvec {T}}}\hat { {\varvec {T}}}\hat { {\varvec {V}}}] in Eq.

NettetIt is well known that the Weyl transformation in a phase space R 21, transforms the elements of L ( R 21) in trace class operators and the elements of L2( R 21) in the Hilbert-Schmidt operators of the Hilbert space L2( R 1); this fact leads to a general method of quantization suggested by E. Wigner and J.E. Moyal and developed by M. Flato, A. …
