Top panels: histogram (scaled to unity) of the phase space density N(Ê,Ĵ_z) for a differentially rotating model characterized by Wilson truncation (left) with , and for one characterized by plain truncation (right) with . Both models are characterized by . Bottom panels: Lindblad diagrams for the same models presented in the top panels. The graphs have been obtained by a Monte Carlo sampling of the relevant distribution functions with 65   536 particles.
