Talk Title: "Augmenting Reality: Axions, Anyons, and Entangled Histories"

Abstract: 

I will give simple introductions to three areas of my current research, where new ideas promise to bring important theoretical ideas to experimental practice. Axions arise in addressing the question why the laws of physics look the same when run backwards in time. They have become a leading candidate to provide the cosmological dark matter. Anyons are emergent particles in two-dimensional systems, which have a sort of memory. Long established (theoretically and numerically) in the fractional quantum hall effect, they are now predicted to occur in spin liquids, where their dynamics will be more accessible. Entangled histories arise in the consideration of a new class of quantum observables, temporal observables, which advances in technology are making accessible. They give concrete, consequential, quantitative meaning to the "many worlds" view of quantum theory.
