Abstracts
We present an overview of gauge fields associated with spin transport and dynamics,
focusing on their origin and physical consequences. Important topics, such as the geometric
gauge fields associated with adiabatic quantum evolution, their “forceful” effects, and their
topological implications are discussed. We would seize the opportunity to study the
ubiquitous application of this theory in “spin” or “spin like” systems like ferromagnet (FM),
metal-FM interface, graphene, and topological insulators. The aim of this talk is to provide an
intuitive and pedagogical insight into the physics of gauge and topology in the modern fields
of nanoscale condensed matter system and devices.
