Abstract
Transport phenomenon in nuclear matter is addressed with
the DYWAN model, which is based on the projection methods of
statistical physics and on the mathematical theory of
wavelets. Strongly compressed representations of the nuclear systems
are obtained with a description of the wave functions and their
antisymmetrization. Fluctuation-dissipation effects are investigated
in nuclear collisions at intermediate energies and comparisons with
experimental data and semi-classical models are presented. The study
of different observables shows that these effects are correctly
described in
and
reactions at different beam energies.
