Surprising Results from Simple Models: Magnetic and Elastic Self Focusing and Biomedical Applications
This dissertation deals with simple approaches to a variety of excitations in materials. The excitations primarily include magnetic spin waves and elastics waves. The key point, however, is the new and interesting applications that can arise in these systems. In particular we develop theoretical descriptions for four main topics:(1) The self-focusing of high-wave-vector magnons(2) The self-focusing of high-wave-vector elastic waves(3) The use of elastic waves to detect impurities through magnetic resonance imaging(4) The nonlinear motion of magnetic nanoparticles in a fluid when driven by an ...
