Particle abundance in a thermal plasma: quantum kinetics vs. Boltzmann equation
D. Boyanovsky, K. Davey, C. M. Ho
We study the abundance of a particle species in a thermalized plasma by introducing a quantum kinetic description based on the non-equilibrium effective action. A stochastic interp…
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…
Particle decay in inflationary cosmology
D. Boyanovsky, H. J. de Vega
We investigate the relaxation and decay of a particle during inflation by implementing the dynamical renormalization group. This investigation allows us to give a meaningful defini…
Oscillations and evolution of a hot and dense gas of flavor neutrinos: a quantum field theory study
D. Boyanovsky, C. M. Ho
We study the time evolution of the distribution functions for hot and or degenerate gases of two flavors of Dirac neutrinos as a result of flavor mixing and dephasing. This is achi…
