Numerical Simulation of Non-Abelian Particle-Field Dynamics
Numerical 1D-3V solutions of the Wong-Yang-Mills equations with anisotropic particle momentum distributions are presented. They confirm the existence of plasma instabilities for weak initial fields and of their saturation at a level where the particle motion is affected, similar to Abelian plasmas. The isotropization of the particle momenta by strong random fields is shown explicitly, as well a...
متن کاملSpacetime Quantization from Non-abelian D-particle Dynamics
We describe the short-distance properties of the spacetime of a system of D-particles by viewing their matrix-valued coordinates as coupling constants of a deformed worldsheet σ-model. We show that the Zamolodchikov metric on the associated moduli space naturally encodes properties of the non-abelian dynamics, and from this we derive new spacetime uncertainty relations directly from the quantum...
متن کاملNumerical Simulation of Dislocation Dynamics – the Stress Field Evaluation Threshold
Abstract. The aim of this contribution is to present the current state of our research in the field of numerical simulation of dislocation motion in crystalline materials. The simulation is based on recent theory treating dislocation curves and dipolar loops interacting by means of forces of elastic nature and hindered by the lattice friction. The motion and interaction of a single parametrical...
متن کاملDynamics of Non-Abelian Vortices
The scattering is studied using moduli space metric for well-separated vortices of nonAbelian vortices in (2+1)-dimensional U(N) gauge theories with N Higgs fields in the fundamental representation. Unlike vortices in the Abelian-Higgs model, dynamics of nonAbelian vortices has a lot of new features; The kinetic energy in real space can be transfered to that of internal orientational moduli and...
متن کاملNumerical simulation of effect of non-spherical particle shape and bed size on hydrodynamics of packed beds
Fluid flow has a fundamental role in the performance of packed bed reactors. Some related issues, such as pressure drop, are strongly affected by porosity, so non-spherical particles are used in industry for enhancement or creation of the desired porosity. In this study, the effects of particle shape, size, and porosity of the bed on the hydrodynamics of packed beds are investigated with three ...
