We discuss the far-from-equilibrium evolution of $\phi^3$-theory in $1+1$ dimensions with the temporal functional renormalisation group \cite{Gasenzer:2007za, Gasenzer:2010rq}. In particular, we show that this manifestly causal approach leads to novel one-loop exact equations for fully dressed correlation functions. Within this setup, we numerically compute the dynamical propagator. Its behaviour suggests self-similarity far from equilibrium in a restricted momentum regime. We discuss the… 
Functional Renormalisation Group for Brownian Motion II: Accelerated Dynamics in and out of Equilibrium
Here we numerically solve the equations derived in part I of this two-part series and verify their validity. In particular we use the functional Renormalisation Group (fRG) flow equations to obtain

Real-time dynamics of the $O(4)$ scalar theory within the fRG approach
In this paper, the real-time dynamics of the O(4)O(4) scalar theory is studied within the functional renormalization group formulated on the Schwinger-Keldysh closed time path. The flow equations for
Renormalizing open quantum field theories
The functional renormalization group flow of a scalar field theory with quartic couplings and a sharp spatial momentum cutoff is presented in four-dimensional Minkowski space-time for the bare action

There has been substantial progress in recent years in the quantitative understanding of the nonequilibrium time evolution of quantum fields. Important topical applications, in particular in high
Stationary, isotropic and homogeneous two-dimensional turbulence: a first non-perturbative renormalization group approach
We study the statistical properties of stationary, isotropic and homogeneous turbulence in two-dimensional (2D) flows, focusing on the direct cascade, that is on large wave-numbers compared to the

In this paper, we present theoretical results on the statistical properties of stationary, homogeneous and isotropic turbulence in incompressible flows in three dimensions. Within the framework of
