The formation of correlations due to collisions in an interacting nucleonic system is investigated. Results from one-time kinetic equations are compared with the Kadanoff and Baym two-time equation with collisions included in Born approximation. A reasonable agreement is found for a proposed approximation of the memory effects by a finite duration of… (More)

Starting from the generalized kinetic equation including complete time evolution , the memory eeect of the collision integral is calculated. It is found, that the innuence of the collisions on the time development of the distribution function is diminished by the non-Markovian behavior of the collision integrals, which is an expression of collision… (More)

The collective motion of a finite nuclear system is investigated by numerical simulation and by linear response theory. Using a pseudo-particle simulation technique we analyze the giant resonances with a multipole decomposition scheme. We examine the energy and the damping of different giant collective modes and obtain the dependence of these quantities on… (More)

The quantum mechanical two-particle problem is considered in hot dense nuclear matter under the innuence of a strong electric eld such as the eld of the residual nucleus in heavy ion reactions. Compared with the in-medium properties in the zero-eld case, bound states are turned into resonances, and the scattering phase shifts are modiied. Three eeects are… (More)

The recently derived nonlocal quantum kinetic equation for dense interacting Fermi systems combines time derivatives with finite time stepping known from the logistic mapping. This continuous delay differential equation is a consequence of the microscopic delay time representing the dynamics of the deterministic chaotic system. The responsible delay time is… (More)
