Abstract
Quantum-classical correspondence for the shape of eigenfunctions, local spe ctral density of states and occupation number distribution is studied in a chaotic model of two coupled quartic oscillators. In particular, it is show n that both classical quantities and quantum spectra determine global prope rties of occupation numbers and inverse participation ratio. (C) 2000 Elsev ier Science B.V.
