Relativistic Effects for Exchange Interactions and Spin-Dynamics Simulation

Explore a comprehensive lecture on mapping electronic structure theory to spin-Hamiltonians and its applications in atomistic magnetization dynamics. Delve into the multiscale method bridging length scales of electronic structure theory and magnetization dynamics theory. Examine various systems with a focus on spin-orbit effects, including skyrmion formation due to the relativistic Dzyaloshinskii-Moriya interaction. Discover the dynamics of skyrmions and learn about a multiscale method combining atomistic and micromagnetic approaches. Gain insights from this 33-minute talk presented by Olle Eriksson at the Workshop on "Spin-Orbit Entangled Quantum Magnetism" held at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI) in September 2024.
