We provide a mathematical analysis of two models advocated in the theoretical and experimental condensed matter literature: the two dimensional spin-1/2 Quantum Walk and the Kagome quantum network; they apply to occurrence of stable quantum currents. This illustrates the theory of stable absolutely continuous spectrum and stable currents developed in \citeABJ5.
