Identification of kinetic order parameters for non-equilibrium dynamics

λφ 4 non - equilibrium dynamics and kinetic field theory 1

Off-shellness and inhomogeneities in the non-equilibrium dynamics of the λϕ 4 model are studied. The non equilibrium field theory is developed in the Closed Time Path formalism, which is in turn reformulated as a kinetic field theory, in terms of a set of kinetic equations for the 2-point Green function, derived from a generalized effective action functional. We take into account all initial co...

Varing chemical equilibrium gives kinetic parameters

We are interested in finding the kinetic parameters of a chemical reaction. Previous methods for finding these parameters rely on the dynamic behaviour of the system. This means that the methods are time-sensitive and often rely on non-linear curve fitting. In the same manner as previous techniques, we consider the concentrations of chemicals in a reaction. However, we investigate the static be...

Kinetic equations governing Smoluchowski dynamics in equilibrium.

We continue our study of the statistical properties of particles in equilibrium obeying Smoluchowski dynamics. We show that the system is governed by a kinetic equation of the memory function form and that the memory function is given by one of the self-energies available via perturbation theory as introduced in previous work. We determine the memory function explicitly to second order in an ex...

Non-equilibrium Molecular Dynamics

Statistical mechanics provides a well-established link between microscopic equilibrium states and thermodynamics. If one considers systems out of equilibrium, the link between microscopic dynamical properties and nonequilibrium macroscopic states is more difficult to establish [1,2]. For systems lying near equilibrium, linear response theory provides a route to derive linear macroscopic laws an...
