- Description
- Thanks to their ubiquity and relative simplicity, magnets have played a central role in our understanding of the collective behaviour of matter. This talk presents very simple magnetic models which host highly unusal dynamical phenomena thanks to an emergent gauge field: one has fractionalised quasiparticles that move on a purely dynamical fractal invisible to thermodynamics; and the other exhibits localisation in the absence of disorder. While the former is based on an existing magnetic material called spin ice, various phenomena in these models -- known and unknown -- are in search of an experimental realisation.
