Condensate decay in a radiation dominated cosmology
Shuyang Cao, Daniel Boyanovsky
We study the decay of a homogeneous condensate of a massive scalar field of mass \emph{m} into massless fields in thermal equilibrium in a radiation dominated cosmology. The model…
Quantum decay in renormalizable field theories: quasiparticle formation, Zeno and anti-Zeno effects
Daniel Boyanovsky
In a renormalizable theory the survival probability of an unstable quantum state features divergences as a consequence of the rapid growth of the density of states with energy. Int…
Information loss in effective field theory: entanglement and thermal entropies
Daniel Boyanovsky
Integrating out high energy degrees of freedom to yield a low energy effective field theory leads to a loss of information with a concomitant increase in entropy. We obtain the eff…
Entanglement entropy in particle decay
Louis Lello, Daniel Boyanovsky, Richard Holman
The decay of a parent particle into two or more daughter particles results in an entangled quantum state as a consequence of conservation laws in the decay process. Recent experime…
Non-Equilibrium Dynamics of Phase Transitions: From the Early Universe to Chiral Condensates
D. Boyanovsky, H. J. de Vega, R. Holman
In this brief review we introduce the methods of quantum field theory out of equilibrium and study the non-equilibrium aspects of phase transitions. Specifically we critically stud…
Quantum Rolling Down out of Equilibrium
D. Boyanovsky, H. J. de Vega
In a scalar field theory, when the tree level potential admits broken symmetry ground states, the quantum corrections to the static effective potential are complex. (The imaginary…
