Temporospatial Dependent Energy Propagation Relative to Torsion Inclusion

ORAL

Abstract

Torsions, a phenomenon where two particles straddle a dust crystal plane while horizontally orbiting a mutual axis, act as a local energy source leading to increased kinetic energy and radial amplitude of the surrounding crystal while also increasing the lattice spacing globally. Multiple torsion inclusions can also lead to non-linear energy amplification, i.e. the increase in energy between any two torsions is greater than double the increase in energy at that distance from a single torsion inclusion. Steady state torsions are suspected of drawing energy from the flow of ions, converting ion streaming energy into dust motion. In this study, torsion induced changes to energy propagation away from an external perturbation is examined. The speed at which this energy propagates away from the perturbation source is determined both towards/through the torsion and as compared to the 'background' regions of the crystal. The amplitude of energy propagated in various directions relative to a single torsion inclusion is also discussed.
