The quantum (ħ =1) and semiclassical (ℏ → 0) Wigner distribution functions were calculated for some anharmonic oscillators using a direct phase‐space variational method.

We present two new derivations of the Wigner distribution function for a simple harmonic oscillator Hamiltonian. Both methods are facilitated using a formula which expresses the Wigner function as a simple trace. The first method of derivation then utilizes a modification of a theorem due to Messiah
