Explore spin dynamics near the field-induced gap-closing transition in one-dimensional magnets in this 40-minute conference talk by Masaki Oshikawa from ISSP-Tokyo. Delivered as part of the Dynamical Response and Transport in Quantum Magnets conference at the Kavli Institute for Theoretical Physics, delve into recent advancements in quantum magnetism. Examine the emergence of low-energy quantum gauge theories controlling collective phenomena in quantum magnets, and investigate challenges such as identifying real materials with novel topologically-ordered states of matter. Analyze dynamical and transport properties revealing fractionalization and multipolar ordering, and consider the roles of disorder and spin-phonon interaction. Explore emergent-electrodynamics induced by topological spin textures, unusual dynamics of integrable systems, and the impact of Moiré systems on 2D quantum magnetism.
