We aim to clarify confusions in the literature as to whether or not dynamical density functional theories for the one-body density of a classical Brownian fluid should contain a stochastic noise term. We point out that a stochastic as well as a deterministic equation of motion for the density ...
It is shown that the dynamical phase structure of such systems consists of five phases. As an example, a one-parameter family is introduced which can be in each of these phases.关键词: Fluctuation phenomena random processes noise and Brownian motion Markov processes DOI: 10.1140/epjb/e2004-...
We introduce a measure of irreversibility we term the entropy production factor to quantify how time reversal symmetry is broken in field theories across scales. We use this scalar, dimensionless function to characterize a dynamical phase transition in simulations of the Brusselator, a prototypical ...
The analog of an individual-based model in soft matter physics is a particle-based simulation, which is used for a microscopic description of a complex fluid. An alternative method used in this area are coarse-grained field theories, which describe in a simplified way the microscopic dynamics th...

Thus, the separation, of the effects of encounters into a dynamical friction and a random fluctuation (which is assumed in the conventional theories of Brownian motion) is explicitly demonstrated from a direct analysis based on the dynamics of the encounters themselves; similary, the ratio of the...
This broad class includes thermal equilibrium systems as well as non-equilibrium systems that can be approximated by effective equilibrium theories72,73. However, such approximations can become inaccurate if probabilistic non-equilibrium fluxes dominate the system dynamics74. For example, reconstructing ...
