“…This limit only holds in the sense of distributions, against integration of appropriate functions (see [36] for a detailed analysis of this limit in the case of the harmonic oscillator). In fact, the Wigner function approaches a delta function in a highly non-trivial way: it decays very fast outside the classical curve, it has a peak approximately at the classical curve, and it oscillates very rapidly around zero inside the curve.…”

“…where W nm (ζ) are the Weyl symbols of the projectors |ψ n ψ m |/2π (the factors of 2π are to keep the notation consistent with standard practice for Wigner functions in the case n = m). For the asymptotically harmonic potential in (1) the functions W nm (ζ) are known analytically (see [24] for example). The Weyl symbol WR(ζ, E) ofR(E) provides a remarkably transparent means of visualising the quantum transmission problem and of relating the scattering matrix to the geometry of classical phase space.…”
