The definition of Wigner distribution is as follows:

For the harmonic oscillator, the time evolution of an arbitrary Wigner distribution is simple.

Wigner distribution may refer to:

Similarly, many systems which exhibit classical chaos have been found with quantum solutions yielding a Wigner distribution, thus supporting the ideas above.

For the kernel of the Wigner distribution function (WDF) is one.

See also Wigner distribution, a disambiguation page.

For instance, the Wigner distribution can and normally does go negative for states which have no classical model-and is a convenient indicator of quantum mechanical interference.

The Wigner distribution gives better auto term localisation compared to the smeared out spectrogram (SP).

The intensity of the light wave, its coherent excitation, is given by the displacement of the Wigner distribution from the origin.

In number-theoretic literature, the Wigner distribution is sometimes called the Sato-Tate distribution.
