The term file dynamics is the motion of many particles in a narrow channel.. In science: in chemistry, physics, mathematics and related fields, file dynamics (sometimes called, single file dynamics) is the diffusion of N (N → ∞) identical Brownian hard spheres in a quasi-one-dimensional channel of length L (L → ∞), such that the spheres do not jump one on top of the other, and the ...
Multi-particle collision dynamics (MPC), also known as stochastic rotation dynamics (SRD), [1] is a particle-based mesoscale simulation technique for complex fluids which fully incorporates thermal fluctuations and hydrodynamic interactions. [2] Coupling of embedded particles to the coarse-grained solvent is achieved through molecular dynamics. [3]
The Robert R. Wilson Prize for Achievement in the Physics of Particle Accelerators is an annual prize established in 1987 by the American Physical Society (APS) to recognize and encourage outstanding achievement, ordinarily by one person but sometimes to two or more physicists who have contributed to the same accomplishment, in the physics of particle accelerators.
A Treatise on the Analytical Dynamics of Particles and Rigid Bodies is a treatise and textbook on analytical dynamics by British mathematician Sir Edmund Taylor Whittaker. Initially published in 1904 by the Cambridge University Press, the book focuses heavily on the three-body problem and has since gone through four editions and has been ...
The mathematical definition of particle methods captures the structural commonalities of all particle methods. [6] It, therefore, allows for formal reasoning across application domains. The definition is structured into three parts: First, the particle method algorithm structure, including structural components, namely data structures, and ...
The principle of work and kinetic energy (also known as the work–energy principle) states that the work done by all forces acting on a particle (the work of the resultant force) equals the change in the kinetic energy of the particle. [26] That is, the work W done by the resultant force on a particle equals the change in the particle's ...
For a system of particles with masses , with coordinates = that constitute a time-dependent random variable, the resulting Langevin equation is [2] [3] ¨ = ˙ + (), where () is the particle interaction potential; is the gradient operator such that () is the force calculated from the particle interaction potentials; the dot is a time derivative ...
Dissipative particle dynamics (DPD) is an off-lattice mesoscopic simulation technique [1] which involves a set of particles moving in continuous space and discrete time. Particles represent whole molecules or fluid regions, rather than single atoms, and atomistic details are not considered relevant to the processes addressed.
