Abstract

We generalize the quantum microcanonical ensemble to the case of complex energy, in order to describe metastable small (finite) systems which can achieve statistical quasi-equilibrium, i.e. for which all of phase space is uniformly but temporarily filled out for a certain period of time. This new ensemble can be applied for instance to the nuclear multifragmentation transition at freeze-out, a state of statistical equilibrium for the duration of the freeze-out time. This ensemble also enables us to widen the application of the Statistical Field Dynamics (SFD) formalism of field theory at finite energy to physical systems with unstable constituents (e.g. Gamow resonances).
