Abstract:

The dynamics of a tridimensional, axially degenerated vibration coupled to a finite Fermi system shaped as a cylindrical reservoir in the Markovian-plus-weak-coupling regime is investigated. The vibration is aimed at representing a normal mode of the fermion system and is extracted out of a hydrodynamical construction for the relative motion of a two-fluid mixture. Such a procedure provides a dispersion relation that has been proven to work properly in nuclear theory. A residual coupling between the mode and the heat reservoir constituted by the single-particle degrees of freedom is adopted and equations of irreversible evolution for the oscillator components and for the fermionic population can be obtained. This dynamical system is numerically integrated for a variety of container sizes and particle numbers and it is shown that thermodynamic magnitudes characterizing the attractor of the dynamical system, as well as typical relaxation times, can be consistently extracted from the numerical approach. © 1986 The American Physical Society.
