@article{Protogenov2013NonlocalES, title={Nonlocal edge state transport in topological insulators}, author={Alexander P. Protogenov and Evgueni V. Chulkov and Valery A. Verbus}, journal={Physical Review B}, year={2013}, volume={88}, pages={195431} }

We use the $N$-terminal scheme for studying the edge-state transport in two-dimensional topological insulators. We find the universal nonlocal response in the ballistic transport approach. This macroscopic exhibition of the topological order offers different areas for applications.
