Nonequilibrium pion dynamics near the critical point in a constituent quark model
D. Boyanovsky, H. J. de Vega, S. -Y. Wang
We study static and dynamical critical phenomena of chiral symmetry breaking in a two-flavor Nambu--Jona-Lasinio constituent quark model. We obtain the low-energy effective action…
Photon production from a thermalized quark gluon plasma: quantum kinetics and nonperturbative aspects
Daniel Boyanovsky, Hector J. de Vega
We study the production of photons from a quark gluon plasma in local thermal equilibrium by introducing a non-perturbative formulation of the real time evolution of the density ma…
The approach to thermalization in the classical phi^4 theory in 1+1 dimensions: energy cascades and universal scaling
D. Boyanovsky, C. Destri, H. J. de Vega
We study the dynamics of thermalization and the approach to equilibrium in the classical phi^4 theory in 1+1 spacetime dimensions. At thermal equilibrium we exploit the equivalence…
Primordial magnetic fields from cosmological phase transitions
D. Boyanovsky, H. J. de Vega, M. Simionato
We study the generation of large scale primordial magnetic fields by a cosmological phase transition during the radiation dominated era. The setting is a theory of N charged scalar…
Are direct photons a clean signal of a thermalized quark gluon plasma?
D. Boyanovsky, H. J. de Vega
Direct photon production from a quark gluon plasma (QGP) in thermal equilibrium is studied directly in real time. In contrast to the usual S-matrix calculations, the real time appr…
Dynamical renormalization group approach to relaxation in quantum field theory
D. Boyanovsky, H. J. de Vega
The real time evolution and relaxation of expectation values of quantum fields and of quantum states are computed as initial value problems by implementing the dynamical renormaliz…
