    Phase transition for the speed of the biased random walk on the supercritical percolation cluster by Fribergh, A, Hammond, A

    Published 2011
    “…We prove the sharpness of the phase transition for speed in the biased random walk on the supercritical percolation cluster on Z^d. That is, for each d at least 2, and for any supercritical parameter p > p_c, we prove the existence of a critical strength for the bias, such that, below this value, the speed is positive, and, above the value, it is zero. …”
