Abstract
In a previous work1 a time-dependent mean-field approximation has been applied to a fermion system with a pairing interaction. It has been shown that this approach provides the main dynamical features of the problem. It can be applied for all values of the coupling strength and number of particles and provides a description valid on both sides of the superconducting phase transition. It clearly points out the phase transition through changes in the phase space trajectories. Moreover, a procedure has been proposed for extracting matrix elements for relevant operators from the variational solution.
