Overview
Explore the intricate world of multipolar magnets in this 40-minute conference talk from the Workshop on "Spin-Orbit Entangled Quantum Magnetism" at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the fascinating interplay between quadrupolar orders and phonons, discovering how this relationship enables the probing and control of multipolar magnets. Examine case studies of various multipolar magnets, including Mott insulators with non-Kramers doublets and higher moment magnets with strong spin-orbit coupling. Learn about cutting-edge research methods, such as Floquet-Magnus expansions and newly developed numerical tools that extend traditional spin-phonon dynamics to SU(N) dynamics coupled with phonons. Gain insights into potential applications of these concepts for tuning magnon or triplon band topology, opening up new possibilities in the field of quantum magnetism.
