It is explained how field-theoretic methods and the dynamic renormalisation group (RG) can be applied to study the universal scaling properties of systems that either undergo a continuous phase transition or display generic scale invariance, both near and far from thermal equilibrium. Part 1 introduces the response functional field theory representation of (nonlinear) Langevin equations. The RG is employed to compute the scaling exponents for several universality classes governing the critical…

It is explained how field-theoretic methods and the dynamic renormalisation group (RG) can be applied to study the universal scaling properties of systems that either undergo a continuous phase
Effects of turbulent mixing on the nonequilibrium critical behaviour
We study the effects of turbulent mixing on the critical behaviour of a nonequilibrium system near its second-order phase transition between the absorbing and fluctuating states. The model describes
Autocorrelation functions in phase-ordering kinetics from local scale invariance
The explicit calculation of the scaling form of the two-time autocorrelation function in phase-ordering kinetics and in those cases of non-equilibrium critical dynamics where the dynamical exponent z
Classical and quantum out-of-equilibrium dynamics. Formalism and applications.
This thesis deals with the dynamics of systems coupled to an environment. We review the symmetries of the Martin-Siggia-Rose-Janssen-deDominicis formalism associated to Langevin equations. In
Population oscillations in spatial stochastic Lotka-Volterra models: A field-theoretic perturbational analysis
In the species coexistence phase, a perturbation expansion with respect to the nonlinear predation rate is employed to demonstrate that spatial degrees of freedom and stochastic noise induce instabilities toward structure formation, and to compute the fluctuation corrections for the oscillation frequency and diffusion coefficient.
Population oscillations in spatial stochastic Lotka–Volterra models: a field-theoretic perturbational analysis
Field theory tools are applied to analytically study fluctuation and correlation effects in spatially extended stochastic predator–prey systems. In the mean-field rate equation approximation, the
Renormalization group study of damping in nonequilibrium field theory
In this paper we shall study whether dissipation in a $\lambda\phi^{4}$ may be described, in the long wavelength, low frequency limit, with a simple Ohmic term $\kappa\dot{\phi}$, as it is usually
Current distribution in systems with anomalous diffusion : renormalization group approach
We investigate the asymptotic properties of the large deviation function of the integrated particle current in systems, in or out of thermal equilibrium, whose dynamics exhibits anomalous diffusion.
Quantum chromodynamics at high energy and noisy traveling waves
When hadrons scatter at high energies, strong color fields, whose dynamics is described by quantum chromodynamics (QCD), are generated at the interaction point. If one represents these fields in


Theory of Branching and Annihilating Random Walks.
A new universality class has been observed in d = 1 for even values of m, when the number of particles is locally conserved modulo 2, and another issue which clearly requires theoretical explanation is the occurrence of a transition at a finite value of σm.

Stochastic non-equilibrium systems
Recent advances in the theory of non-equilibrium systems are reviewed. The emphasis is on collective behaviour, particularly non-equilibrium stochastic dynamics and steady state phase transitions.
Statistical Dynamics of Classical Systems
The statistical dynamics of a classical random variable that satisfies a nonlinear equation of motion is recast in terms of closed self-consistent equations in which only the observable correlations
Scaling and Renormalization in Statistical Physics
This text provides a thoroughly modern graduate-level introduction to the theory of critical behaviour. Beginning with a brief review of phase transitions in simple systems and of mean field theory,
Theory of dynamic critical phenomena
An introductory review of the central ideas in the modern theory of dynamic critical phenomena is followed by a more detailed account of recent developments in the field. The concepts of the
Non-equilibrium critical phenomena and phase transitions into absorbing states
This review addresses recent developments in non-equilibrium statistical physics. Focusing on phase transitions from fluctuating phases into absorbing states, the universality class of directed
Renormalization group study of theA+B→⊘ diffusion-limited reaction
AbstractTheA+B→⊘ diffusion-limited reaction, with equal initial densitiesa(0)=b(0)=n0, is studied by means of a field-theoretic renormalization group formulation of the problem. For dimensiond>2 an
Fixed-Point Hamiltonian for a Randomly Driven Diffusive System
We consider the universal behavior of a system of interacting particles, diffusing under the influence of thermal noise and a random external field which drives the system into a non-equilibrium
