Low-dissipation edge currents without edge states

We propose that bulk free carriers in topologically trivial multivalley insulators with nonvanishing Berry curvature can give rise to low-dissipation edge currents, which are squeezed within a distance on the order of the valley diffusion length from the edge. This happens even in the absence of edg...
