Journal ArticleDOI
Non-perturbative renormalization flow in quantum field theory and statistical physics
TL;DR: In this paper, the use of exact renormalization group equation in quantum field theory and statistical physics is reviewed. But the authors focus on the second-order phase transition and the critical behavior of polymer chains, and do not consider the non-perturbative solutions of the coarse-grained free energy.
Proceedings ArticleDOI
Introduction to Nonequilibrium Quantum Field Theory
TL;DR: In this paper, functional integral techniques are used to connect the far-from-equilibrium dynamics at early times with the approach to thermal equilibrium at late times, which is crucial for a wide range of phenomena.
Journal ArticleDOI
Color superconductivity and chiral symmetry restoration at non-zero baryon density and temperature☆
Juergen Berges,Krishna Rajagopal +1 more
TL;DR: In this article, the phase diagram of strongly interacting matter as a function of temperature and baryon number density is explored, using a class of models for two-flavor QCD in which the interaction between quarks is modelled by that induced by instantons.
Journal ArticleDOI
Nonthermal Fixed Points: Effective Weak Coupling for Strongly Correlated Systems Far from Equilibrium
TL;DR: Strongly correlated systems far from equilibrium can exhibit scaling solutions with a dynamically generated weak coupling by investigating isolated systems described by relativistic quantum field theories for initial conditions leading to nonequilibrium instabilities, such as parametric resonance or spinodal decomposition.
Journal ArticleDOI
Controlled nonperturbative dynamics of quantum fields out of equilibrium
TL;DR: In this paper, the authors compute the real-time evolution of an O (N )-symmetric scalar quantum field theory from a systematic 1/N expansion of the 2PI effective action to next-to-leading order, which includes scattering and memory effects.
