3D topological insulator nanowires can nowadays be shaped at the nanoscale, so that protected Dirac electrons propagate on curved non-trivial surfaces. In such novel topological platforms physical curvature is as crucial as quantum (Berry) geometrical properties, and transport is defined by competition/cooperation between the two.
