Shane Sandhoefner will present his comprehensive exam, “Topological Magnons in Collinear and Noncollinear Magnets”
Zoom Meeting: https://unl.zoom.us/j/95922960136 (Meeting ID: 959 2296 0136)
Abstract:
Topological insulators, which are insulating in the bulk but conducting at the edges and protected by topological considerations, have been an area of great research interest for many years. The carriers in these systems are typically charged and fermionic. Recent years have seen efforts to extend the concept of topology to chargeless, bosonic states, such as magnons. In this review, I discuss important properties of topological insulators, review the ways in which these concepts have been extended to magnons, and consider several types of systems which have been proposed to give rise to topological magnons. I also discuss future research possibilities.
