The Poisson structure of the mean-field equations in the Phi4 theory
Abstract
We show that the mean-field time dependent equations in the Phi4 theory can be put into a classical non-canonical hamiltonian framework with a Poisson structure which is a generalization of the standard Poisson bracket. The Heisenberg invariant appears as a structural invariant of the Poisson tensor. (To be pubished in Annals of Physics)
