Nonequilibrium relaxation of Bose-Einstein condensates: Real-time equations of motion and Ward identities
D. Boyanovsky, S. -Y. Wang, D. -S. Lee +2
We present a field-theoretical method to obtain consistently the equations of motion for small amplitude condensate perturbations in a homogeneous Bose-condensed gas directly in re…
Dynamics near the critical point: the hot renormalization group in quantum field theory
D. Boyanovsky, H. J. de Vega
The perturbative approach to the description of long wavelength excitations at high temperature breaks down near the critical point of a second order phase transition. We study the…
Non-Equilibrium Large N Yukawa Dynamics: marching through the Landau pole
Daniel Boyanovsky, Hector J. de Vega, Richard Holman +1
The non-equilibrium dynamics of a Yukawa theory with N fermions coupled to a scalar field is studied in the large N limit with the goal of comparing the dynamics predicted from the…
Dynamical renormalization group approach to the Altarelli-Parisi-Lipatov equations
D. Boyanovsky, H. J. de Vega, D. -S. Lee +2
The Altarelli-Parisi-Lipatov equations for the parton distribution functions are rederived using the dynamical renormalization group approach to quantum kinetics. This method syste…
Phase transitions in the early and the present Universe: from the big bang to heavy ion collisions
D. Boyanovsky
In these lectures I discuss cosmological phase transitions with the goal of establishing the possibility of observational consequences. I argue that the {\em only} phase transition…
Inflation from Tsunami-waves
D. Boyanovsky, F. J. Cao, H. J. de Vega
We investigate inflation driven by the evolution of highly excited quantum states within the framework of out of equilibrium field dynamics. These states are characterized by a non…
Direct photons: a nonequilibrium signal of the expanding quark-gluon plasma
Shang-Yung Wang, Daniel Boyanovsky, Kin-Wang Ng
Direct photon production from a longitudinally expanding quark-gluon plasma (QGP) at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies is studied with…
