Non-positivity of the Wigner function and bounds on associated integrals
A. J. Bracken, D. Ellinas, J. G. Wood
The Wigner function shares several properties with classical distribution functions on phase space, but is not positive-definite. The integral of the Wigner function over a given r…

Group Theory and Quasiprobability Integrals of Wigner Functions
A. J. Bracken, D. Ellinas, J. G. Wood
The integral of the Wigner function of a quantum mechanical system over a region or its boundary in the classical phase plane, is called a quasiprobability integral. Unlike a true…
