Pushing-Induced Arrest Across Lattices and Dimensions (opens in new tab)

arXiv:2603.04048v1 Announce Type: new Abstract: Tracer-media interactions can give rise to transport phenomena beyond classical models; e.g., obstacle pushing can eliminate percolation. We demonstrate that the existing explanation of this effect fails in 3D. We show that confinement is governed by emergent trapping-rare door-closing events with constant probability per step-yielding exponential survival. This allows prediction of the time-dependent mean-squared displacement from short-time e...
