Neutrino Oscillations in the Early Universe: A Real Time Formulation
C. M. Ho, D. Boyanovsky, H. J. de Vega
Neutrino oscillations in the early Universe prior to the epoch of primordial nucleosynthesis is studied by implementing real time non-equilibrium field theory methods. We focus on…
Quantum corrections to the inflaton potential and the power spectra from superhorizon modes and trace anomalies
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
We obtain the effective inflaton potential during slow roll inflation by including the one loop quantum corrections to the energy momentum tensor from scalar curvature and tensor p…
The Classical and Quantum Inflaton: the Precise Inflationary Potential and Quantum Inflaton Decay after WMAP
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
We clarify classical inflaton models by considering them as effective field theories `a la Ginzburg-Landau. In this approach, the WMAP statement excluding the pure phi^4 potential…
Quantum corrections to slow roll inflation and new scaling of superhorizon fluctuations
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
Precise cosmological data from WMAP and forthcoming CMB experiments motivate the study of the quantum corrections to the slowroll inflationary parameters.We find the quantum (loop)…
Particle decay during inflation: self-decay of inflaton quantum fluctuations during slow roll
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
Particle decay during inflation is studied by implementing a dynamical renormalization group resummation combined with a small Delta expansion. Delta measures the deviation from th…
Dynamical renormalization group approach to relaxation in quantum field theory
D. Boyanovsky, H. J. de Vega
The real time evolution and relaxation of expectation values of quantum fields and of quantum states are computed as initial value problems by implementing the dynamical renormaliz…
