A Non-intersecting Random Walk on the Manhattan Lattice and SLE 6

Research output: Contribution to journalArticlepeer-review


We consider a random walk on the Manhattan lattice. The walker must follow the orientations of the bonds in this lattice, and the walker is not allowed to visit a site more than once. When both possible steps are allowed, the walker chooses between them with equal probability. The walks generated by this model are known to be related to interfaces for bond percolation on a square lattice. So it is natural to conjecture that the scaling limit is SLE 6. We test this conjecture with Monte Carlo simulations of the random walk model and find strong support for the conjecture.
