1Ising model — The Ising model, named after the physicist Ernst Ising, is a mathematical model in statistical mechanics. It has since been used to model diverse phenomena in which bits of information, interacting in pairs, produce collectiveeffects.Definition… …
2Langevin equation — In statistical physics, a Langevin equation (Paul Langevin, 1908) is a stochastic differential equation describing the time evolution of a subset of the degrees of freedom. These degrees of freedom typically are collective (macroscopic) variables …
3analysis — /euh nal euh sis/, n., pl. analyses / seez /. 1. the separating of any material or abstract entity into its constituent elements (opposed to synthesis). 2. this process as a method of studying the nature of something or of determining its… …
4Reynolds-averaged Navier–Stokes equations — The Reynolds averaged Navier–Stokes (RANS) equations are time averaged [The true time average ( ar{X} ) of a variable ( x ) is defined by: ar{X} = lim {T o infty}frac{1}{T}int {t 0}^{t 0+T} x, dt. For this to be a well defined term, the limit ( …
5Molecular dynamics — (MD) is a computer simulation of physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a period of time, giving a view of the motion of the atoms. In the most common version, the trajectories of molecules… …
6Path integral formulation — This article is about a formulation of quantum mechanics. For integrals along a path, also known as line or contour integrals, see line integral. The path integral formulation of quantum mechanics is a description of quantum theory which… …

8Dissipation model for extended environment — (a) The Brownian particle in the Caldeira Leggett model experiences a fluctuating homogeneous field of force. (b) In case of the DLD model the fluctuating field is farther characterized by a finite correlation distance. The background image is a… …
9Lift (force) — For other uses, see Lift. Boeing 747 8F landing A fluid flowing past the surface of a body exerts a surface force on it. Lift is the component of this force that is perpendicular to the …
