Asymmetric diffusion of magnetic skyrmions in a structured chamber

Caption

Magnetic skyrmions diffuse more easily from the left chamber to the right chamber owing to their nontrivial random-walk dynamics and topology-dependent interactions with the off-center asymmetric gate. This mechanism offers a promising route toward unconventional artificial intelligence hardware.
