Spinor formulation of the Landau-Lifshitz-Gilbert equation with geometric algebra
arXiv:2501.03798 · doi:10.1109/TMAG.2024.3509214
Abstract
The Landau-Lifshitz-Gilbert equation for magnetization dynamics is recast into spinor form using the real-valued Clifford algebra (geometric algebra) of three-space. We show how the undamped case can be explicitly solved to obtain component-wise solutions, with clear geometrical meaning. Generalizations of the approach to include damping are formulated. The implications of the axial property of the magnetization vector are briefly discussed.
