Statistical properties of fermionic molecular dynamics

Statistical properties of Fermionic Molecular Dynamics are studied. It is shown that, although the centroids of the single-particle wave-packets follow classical trajectories in the case of a harmonic oscillator potential, the equilibrium properties of the system are the quantum mechanical ones. A system of weakly interacting fermions as well as of distinguishable particles is found to be ergodic and the time-averaged expectation values approach the quantum canonical ones of Fermi-Dirac and Boltzmann statistics, respectively. This equivalence also attributes a temperature to the pure many-body states.
