Anomalous Kinetics of Hard Charged Particles: Dynamical Renormalization Group Resummation
D. Boyanovsky, H. J. de Vega
We study the kinetics of the distribution function for charged particles of hard momentum in scalar QED. The goal is to understand the effects of infrared divergences associated wi…
Non-Equilibrium Bose-Einstein Condensates, Dynamical Scaling and Symmetric Evolution in large N Phi^4 theory
D. Boyanovsky, H. J. de Vega, R. Holman +1
We analyze the non-equilibrium dynamics of the O(N) Phi^4 model in the large N limit and for states of large energy density. The dynamics is dramatically different when the energy…
Fermion Damping in a Fermion-Scalar Plasma
D. Boyanovsky, H. J. de Vega, Y. J. Ng +2
In this article we study the dynamics of fermions in a fermion-scalar plasma. We begin by obtaining the effective in-medium Dirac equation in real time which is fully renormalized…
Non-Equilibrium Real-Time Dynamics of Quantum Fields: Linear and Non-Linear Relaxation in Scalar and Gauge Theories
D. Boyanovsky, H. J. de Vega, R. Holman +3
The real time evolution of field condensates is solved for small and large field amplitudes in scalar theories.For small amplitudes,the quantum equations of motion for the condensa…
Dynamical renormalization group resummation of finite temperature infrared divergences
D. Boyanovsky, H. J. de Vega, R. Holman +1
We introduce the method of dynamical renormalization group to study relaxation and damping out of equilibrium directly in real time and applied it to the study of infrared divergen…
Quantum kinetics and thermalization in an exactly solvable model
S. M. Alamoudi, D. Boyanovsky, H. J. de Vega +1
We study the dynamics of relaxation and thermalization in an exactly solvable model with the goal of understanding the effects of off-shell processes. The focus is to compare the e…
Real-time Relaxation and Kinetics in Hot Scalar QED: Landau Damping
Daniel Boyanovsky, Hector J. de Vega, Richard Holman +2
The real time evolution of field condensates with soft length scales k^{-1}>(eT)^{-1} is solved in hot scalar electrodynamics, with a view towards understanding relaxational phenom…
Evolution of Inhomogeneous Condensates: Self-consistent Variational Approach
D. Boyanovsky, F. Cooper, H. J. de Vega +1
We establish a self-consistent variational framework that allows us to study numerically the non-equilibrium evolution of non-perturbative inhomogeneous field configurations includ…
Out of Equilibrium Fields in Inflationary Dynamics. Density Fluctuations
D. Boyanovsky, D. Cormier, H. J. de Vega +2
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 make…
