From: Stochastic dynamics and pattern formation of geometrically confined skyrmions
Fast deformation dynamics of two skyrmions on a disk-shaped island. Two skyrmions on a single disk (21 × 21 × 0.4) nm3 are initialized from a relaxed zero-temperature configuration. Afterward, 50 different seeds for the pseudorandom number generator are used to simulate the skyrmion dynamics over 100 ps, saved every 0.5 ps. The results are analyzed by calculating the centers of the skyrmions, followed by the computation of the average skyrmion radius (see Methods) for each of them as shown in a and b. Averaging over the different simulations smears out most of the pure stochastic dynamics, yielding an oscillating pattern superposed with a general trend of an increased skyrmion radius compared to the zero-temperature configuration. Bright blue points show data averaged over different simulations, the solid blue line corresponds to data smoothened by a Gaussian filter in order to calculate the peak positions (red dots)
