Magnetic And Optical Holonomic Manipulation Of Colloids, Structures And Topological Defects In Liquid Crystals For Characterization Of Mesoscale Self-Assembly And Dynamics, Michael Christopher Mason Varney

Physics Graduate Theses & Dissertations

Colloidal systems find important applications ranging from fabrication of photonic crystals to direct probing of phenomena encountered in atomic crystals and glasses; topics of great interest for physicists exploring a broad range of scientific, industrial and biomedical fields. The ability to accurately control particles of mesoscale size in various liquid host media is usually accomplished through optical trapping methods, which suffer limitations intrinsic to trap laser intensity and force generation. Other limitations are due to colloid properties, such as optical absorptivity, and host properties, such as viscosity, opacity and structure. Therefore, alternative and/or novel methods of colloidal manipulation are ...
