Master's Thesis Presentation
Classical Scattering of Charges in the Presence of a Magnetic Monopole
Yigal Weinstein
B.A. 2003, UC Santa Cruz
Tuesday, July 1, 2008
1:00PM, Room PH2-110
We consider the classical scattering of monoenergetic charges emitted from an isotropic point source in a magnetic monopole field. Individual paths are geodesics on a guiding cone (Poincare). However, the scattering characteristics depend on the entire field of trajectories emitted in different directions from the source.
The trajectories trace out a complex geometrical pattern ordered by an infinite sequence of turning surfaces, classical boundaries of motion that represent singularities of the scattering cross section and shape the density profile. They are closely related to the caustics of wave optics. We present numerical and analytical results from trajectories, caustics, and density maps.
Our study are a prerequisite for the future semiclassical treatment of electron waves in the monopole field.
