Paper Abstract

Optical traps have been extensively employed to create tailored colloidal crystalline structures where the crystals can have long range order. Here we discuss how colloidal particles on periodic substrates can be used to understand how frustration can produce partially ordered states. We demonstrate how to create artificial spin ice systems using colloidal particles and describe variations on this system that include geometries in which a random loop model can be realized. We also discuss how frustration effects can be used to control grain boundary formation by creating energetic defects in the ground state ordering of these systems.
