Abstract
An explicit expression is given for the exact eigenstate Wigner functions of a whole class of non-integrable quantum systems with m degrees of freedom. Their evaluation only needs finite matrix diagonalisation, without any truncation error. The application of this expression is illustrated for the m = 2 integrable case, which reproduces the expected semiclassical behaviour.File in questo prodotto:
