Enhanced colloidal transport in twisted magnetic patterns

Abstract

Twisted bilayer systems, where superconductivity can be realised in two layers of graphene twisted in orientation to each other at a ‘magic’ angle, has triggered a flurry of investigations that encompass an increasing range of different materials and complex setups. Here, the authors theoretically propose an analogous system of twisted magnetic patterns which result in the enhanced mobility of colloidal particles at specific twist angles.
