Interplay of transport and domain walls in nodal semimetals

Topological band structures are well-known to induce exotic bound states at their surfaces. With this in mind, it is natural to expect that magnetic domain walls can play a similar role *inside* a material. Here we report on theoretical studies of the transport in magnetic Weyl systems with domain walls, and how this leads to a number of physical effects. The applications to experiments on Mn3Sn and CeAlGe will be discussed.
