A microscopic view on cosmic structure formation
Adopting methods familiar from non-equilibrium quantum field theory, we have developed a microscopic, non-equilibrium field theory for cosmic structure formation. The theory begins with the initial phase-space distribution of a correlated ensemble of classical particles undergoing Hamiltonian dynamics. This phase-space distribution defines a generating functional resembling the partition function familiar from thermodynamics. With the free Green's function of the Hamiltonian equations, the free generating functional can be evolved in time, and particle interactions can be taken into account by
