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 ...
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.
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 ...
Eric R. Weeks (born 1970 in Downers Grove, Illinois) is an American physicist.He completed his B.Sc. at the University of Illinois at Urbana–Champaign in 1992. He obtained a Ph.D. in physics from the University of Texas at Austin in 1997, working under Harry Swinney, and later completed post-doctoral research with David Weitz and Arjun Yodh at Harvard University and the University of ...
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 ...
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.
The work of a force on a particle along a virtual displacement is known as the virtual work. Historically, virtual work and the associated calculus of variations were formulated to analyze systems of rigid bodies, [ 1 ] but they have also been developed for the study of the mechanics of deformable bodies.
