Energy Density Fluctuations in Inflationary Cosmology
We analyze the energy density fluctuations contributed by scalar fields Φ with vanishing expectation values, 〈Φ〉 = 0, which are present in addition to the inflaton field. For simplicity we take Φ to be non–interacting and minimally coupled to gravity. We use normal ordering to define the renormalized energy density operator ρ, and we show that any normal ordering gives the same result for corre...
متن کاملDensity Fluctuations in Inflationary Models with Multiple Scalar Fields
Making use of the primordially isocurvature fluctuations, which are generated in inflationary models with multiple scalar fields, we make a phenomenological model that predicts formation of primordial black holes which can account for the massive compact halo objects recently observed. In inflationary universe models [1] with multiple scalar fields, not only adiabatic [2] but also primordially ...
متن کاملLeptogenesis in Inflationary Universe
We investigate the leptogenesis via decays of heavy Majorana neutrinos which are produced non-thermally in inflaton decays. We make a comprehensive study on the leptogenesis assuming various supersymmetric (SUSY) models for hybrid, new and topological inflations. For an estimation of the lepton asymmetry we adopt the Froggatt-Nielsen mechanism for mass matrices of quarks and leptons. We find th...
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...
