Sterile neutrino production via active-sterile oscillations: the quantum Zeno effect
D. Boyanovsky, C. M. Ho
We study several aspects of the kinetic approach to sterile neutrino production via active-sterile mixing. We obtain the neutrino propagator in the medium including self-energy cor…
Non equilibrium dynamics of mixing, oscillations and equilibration: a model study
D. Boyanovsky, C. M. Ho
The non-equilibrium dynamics of mixing, oscillations and equilibration is studied in a field theory of flavored neutral mesons that effectively models two flavors of mixed neutrino…
CMB quadrupole suppression: I. Initial conditions of inflationary perturbations
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
We investigate the issue of initial conditions of curvature and tensor perturba- tions at the beginning of slow roll inflation and their effect on the power spectra. Renormalizabil…
CMB quadrupole suppression: II. The early fast roll stage
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
Within the effective field theory of inflation, an initialization of the classical dynamics of the inflaton with approximate equipartition between the kinetic and potential energy…
Space-time propagation of neutrino wave packets at high temperature and density
C. M. Ho, D. Boyanovsky
We study the space-time evolution of ``flavor'' neutrino wave-packets at finite temperature and density in the early Universe prior to BBN. We implement non-equilibrium field theor…
Phase transitions in the early and the present Universe
D. Boyanovsky, H. J. de Vega, D. J. Schwarz
The evolution of the Universe is the ultimate laboratory to study fundamental physics across energy scales that span about 25 orders of magnitude: from the grand unification scale…
Clarifying Slow Roll Inflation and the Quantum Corrections to the Observable Power Spectra
D. Boyanovsky, H. J. de Vega, N. G. Sanchez
Slow-roll inflation can be studied as an effective field theory. The form of the inflaton potential consistent with the data is V(phi) = N M^4 w(phi/[sqrt{N} M_{Pl}]) where phi is…
