Observation of SLE(κ, ρ) on the critical statistical models

Schramm–Loewner evolution (SLE) is a stochastic process that helps classify critical statistical models using one real parameter κ. Numerical study of SLE often involves curves that start and end on the real axis. To reduce numerical errors in studying the critical curves which start from the real axis and end on it, we have used hydrodynamically normalized SLE(κ, ρ) which is a stochastic differential equation governing such curves. In this paper, we directly verify this hypothesis and numerically apply this formalism to the domain wall curves of the Abelian sandpile model (κ = 2) and critical percolation (κ = 6). We observe that this method is more reliable than previously used methods in the literature for analyzing interface loops. (paper)
