Generalizing Thiele equation

POSTER

Abstract

Recent systematic experimental results indicate a significant disparity between the skyrmion Hall angles with positive and negative topological charges. Conventional Thiele equation is not suitable for explaining the disparity. We propose a direct generalization of the Thiele equation with a transverse component of the collective coordinate of skyrmion center. The generalized Thiele equation successfully accommodate the disparity in the skyrmiin Hall angles.
