Non-equilibrium phase transitions in condensed matter and cosmology: spinodal decomposition, condensates and defects
D. Boyanovsky, H. J. de Vega, R. Holman
These lectures address the dynamics of phase ordering out of equilibrium in condensed matter and in quantum field theory in cosmological settings, emphasizing their similarities an…
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…
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…
Preheating in FRW Universes
D. Boyanovsky, D. Cormier, H. J. de Vega +3
The nonlinear time evolution of the quantum fields is studied in the O(N) model for large N in a radiation dominated FRW universe, with a view towards the phenomenon of explosive p…
Reply to: Comments on ``Analytic and Numerical Study of Preheating Dynamics''
D. Boyanovsky, H. J. de Vega, R. Holman
Reply to the comment by L. Kofman, A. Linde and A.A. Starobinsky (hep-ph/9608341) to our article ``Analytic and Numerical Study of Preheating Dynamics'' (hep-ph/9608205).
Dynamics of Cosmological Phase Transitions
D. Boyanovsky, H. J. de Vega, R. Holman
The dynamics of typical phase transitions is studied out of equilibrium in weakly coupled inflaton-type scalar field theories in Minkowski space. The shortcomings of the effective…
