Title: Effect of the Magnus force on skyrmion relaxation dynamics

Abstract

We perform systematic Langevin molecular dynamics simulations of interacting skyrmions in thin films. The interplay between the Magnus force, the repulsive skyrmion-skyrmion interaction, and the thermal noise yields different regimes during nonequilibrium relaxation. In the noise-dominated regime, the Magnus force enhances the disordering effects of the thermal noise. In the Magnus-force-dominated regime, theMagnus force cooperates with the skyrmion-skyrmion interaction to yield a dynamic regime with slow decaying correlations. Furthermore, these two regimes are characterized by different values of the aging exponent. In general, the Magnus force accelerates the approach to the steady state.
