Out of equilibrium quantum field dynamics in external fields
The quantum dynamics of the symmetry broken λ(Φ) scalar field theory in the presence of an homogeneous external field is investigated in the large N limit. We consider an initial thermal state of temperature T for a constant external field J . A subsequent sign flip of the external field, J → −J , gives rise to an out of equilibrium nonperturbative quantum field dynamics. We review here the dyn...
متن کاملOut of Equilibrium Non-perturbative Quantum Field Dynamics in Homogeneous External Fields
The quantum dynamics of the symmetry broken λ (~ Φ2)2 scalar field theory in the presence of an homogeneous external field is investigated in the large N limit. We choose as initial state the ground state for a constant external field ~ J . The sign of the external field is suddenly flipped from ~ J to − ~ J at a given time and the subsequent quantum dynamics calculated. Spinodal instabilities ...
متن کاملControlled nonperturbative dynamics of quantum fields out of equilibrium
We compute the nonequilibrium real-time evolution of an O(N)–symmetric scalar quantum field theory from a systematic 1/N expansion of the 2PI effective action to next-to-leading order, which includes scattering and memory effects. In contrast to the standard 1/N expansion of the 1PI effective action, the next-toleading order expansion in presence of a possible expectation value for the composit...
متن کاملOut of Equilibrium Fields in Selfconsistent Inflationary Dynamics. Density Fluctuations
The physics during the inflationary stage of the universe is of quantum nature involving extremely high energy densities. Moreover, it is out of equilibrium on a fastly expanding dynamical geometry. We present in these lectures non-perturbative out of equilibrium field theoretical methods in cosmological universes. We then study the non-linear dynamics of quantum fields in matter and radiation ...
متن کاملOut of Equilibrium Fields in Inflationary Dynamics. Density Fluctuations
The energy and time scales during the inflationary stage of the universe calls for an out of equilibrium quantum field treatment. Moreover, the high energy densities involved (∼ 1/g ∼ 1012) make necessary the use of non-perturbative approaches as the large N and Hartree methods. We start these lectures by introducing the such non-perturbative out of equilibrium methods in cosmological universes...
