%0 Journal Article %T SLE(6) and the geometry of diffusion fronts %A Pierre Nolin %J Mathematics %D 2009 %I arXiv %X We study the diffusion front for a natural two-dimensional model where many particles starting at the origin diffuse independently. It turns out that this model can be described using properties of near-critical percolation, and provides a natural example where critical fractal geometries spontaneously arise. %U http://arxiv.org/abs/0912.3770v1
