A hierarchy of sum-rules in out of equilibrium QFT
Julien F. J. Salgado
Generalising a result of classical mechanics an infinite set of conserved quantities can be found for the bare equations of motion describing the evolution of a scalar field in out…
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…
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…
Asymptotic Dynamics in Scalar Field Theory: Anomalous Relaxation
D. Boyanovsky, C. Destri, H. J. de Vega +2
We analyze the dynamics of dissipation and relaxation in the unbroken and broken symmetry phases of scalar theory in the nonlinear regime for large initial energy densities, and af…
Order parameter evolution in scalar QFT: renormalization group resummation of secular terms
H. J. de Vega, J. F. J. Salgado
The quantum evolution equations for the field expectation value are analytically solved to cubic order in the field amplitude and to one-loop level in the lambda phi-fourth model.…
Preheating and Reheating in Inflationary Cosmology: a pedagogical survey
D. Boyanovsky, H. J. de Vega, R. Holman +1
Recent progress in the preheating phenomena for inflationary cosmology is reviewed. We first discuss estimates of the preheating time scale and particle production at the early sta…
