Nonhermitian adiabatic perturbation theory of topological quantization of the average velocity of a magnetic skyrmion under thermal fluctuations
Shan-Chang Tang, Yu Shi
We study the two-dimensional motion of a magnetic skyrmion driven by a ratchetlike polarized electric current that is periodic in both space and time. Some general cases are consid…

Topological quantization of the flow of magnetic skyrmions driven by a ratchet-like potential under thermal fluctuations
Shan-Chang Tang, Yu Shi
We consider a magnetic skyrmion adiabatically driven by a spin-polarized electrical current periodic in both space and time and asymmetric in space, and also subject to a random ma…
