Correlated initial condition for an embededded process by time partitioning
Result description
tudy of transients in the electron quantum transport by Non-Equilibrium Green's Functions (NGF) often requires an explicit inclusion of correlations at a finite initial time. For processes embedded in a host process, a universal treatment of the correlated initial conditions based on the formalism of partitioning in time allows to express their self-energy including the "irregular" correlation part in terms of the known properties of the host process. This unified formalism also yields the renormalizedsemi-group property for propagators and the reconstruction equations for the particle correlation function. The Bogolyubov principle of the decay of correlations then permits to build up a theory of quantum transport equations with finite time initial conditions.
