In two dimensions, we give an upper bound on the chemical distance between the two boundaries of a macroscopic annulus. Our bound holds with high probability conditioned on connectivity and the bound is sharp up to a poly-logarithmic factor with an exponent of one-quarter. This substantially improves a previous result by Li and the first author. In three dimensions and higher, we provide rather sharp estimates of percolation probabilities in different regimes which altogether describe a sharp phase transition.", "revisions": [ { "version": "v1", "updated": "2018-07-29T22:48:20.000Z" } ], "analyses": { "subjects": [ "60G60", "60K35" ], "keywords": [ "gaussian free fields", "metric graphs", "study level-set percolation", "sharp phase transition", "macroscopic annulus" ], "note": { "typesetting": "TeX", "pages": 29, "language": "en", "license": "arXiv", "status": "editable" } } }
