Classical chaos effect on nuclear collective motion

Radionov, Sergey LU (2006) In Physica Scripta T125. p.151-157
Abstract
Here, the problem of the classical chaos effect on dissipation in nuclear many-body systems is addressed. To investigate this problem, the energy response on parametric driving of external confinement of the simplest interacting many-body system is studied: two identical like-charged particles moving on the plane in the field of a deformed harmonic oscillator, which shows a rich structure of the classical phase space. The parametric driving is represented by the slow periodic modulation of the deformation of confinement. Here, the focus is on how the driven dynamics of particles is defined by the structure of the unperturbed phase space of the system. It has been found that the rate at which the energy of the external driving is pumped... (More)

Here, the focus is on how the driven dynamics of particles is defined by the structure of the unperturbed phase space of the system. It has been found that the rate at which the energy of the external driving is pumped into the energy of the interacting two-body system strongly depends on the driven dynamics of the regular orbits. A role of interaction for the energy absorption rate is also discussed. (Less)
