Semi-slippery obstacles in 2D. Varied the bound diffusion coefficient from the sticky Dbound = 0 to slippery Dbound = Dfree limit for single site lobst = 1 obstacles. Top panel: (a, d) Diffusion coefficient D*, (b, e) anomalous time ta, and (c, f) minimum scaling exponent αmin as function of Dbound for low filling fraction ν = 0.3 (top) and high filling fraction ν = 0.6 (bottom).
