The formation of nuclear fragments in intermediate energy heavy ion reactions is studied within a molecular dynamics model, recently developed in Copenhagen. Observable characteristics such as fragment mass distributions, multiplicities of intermedia

Central and semi-central Au + Au collisions at 150 and 250 A ·MeV are investigated in the framework of a hybrid model with dynamical and statistical components. Starting from the BUU approach and ansatz for the Wigner function is made which describe

The fragment-fragment correlation is investigated for nearly central collisions of Au on Au at 150 MeV per nucleon. The properties of the fragmenting source are determined within the Boltzmann-Uhling-Uhlenbeck approach. The final decay is described b

The correlations between the charges emitted in the collision of 600 A.MeV Au nuclei on different targets are analysed by using a statistical multifragmentation model. Those correlations in partition space can be well reproduced by adjusting source s

The hadronization process of an expanding quark-gluon plasma is studied within two different non-equilibrium approaches. In the flavour kinetic model, we consider a bulk transition mechanism including resonance decay and particle evaporation, while i

For the reaction of 16 O and 36 Ar with the AgBr component of emulsion at 210±10 MeV and 65±15 MeV per nucleon, respectively, the fragments' charge and emission angle have been measured. An additional momentum-flow-tensor analysis provides a strict

Fluctuation pattern in nuclear multifragmentation events might carry information about the nature of the fragmentation process. In the present work we discuss implications of the ergodicity assumption implicity assumed in the equilibrium approaches t

Nuclear multifragmentation processes may show features such as intermittency that signal scale-invariant properties of fluctuations in the fragment distributions. We test this behavior using several models and show that intermittency may be caused by

We examine the in-medium scattering cross section in a dense and hot pionic gas. We show that the increase of the scattering rate associated with the Bose occupancy factors is largely compensated by a drop in the cross section, when medium effects on
