Using a central limit theorem for dependent random variables we find the precise conditions for the model to belong to the universality class of the Totally Asymmetric Oslo model, thereby identifying a large universality class of directed sandpiles. We map the avalanche size to the area under a Brownian curve with an absorbing boundary at the origin, motivating us to solve this Brownian curve problem. Thus, we are able to determine the moment generating function for the avalanche-size probability in this universality class, explicitly calculating amplitudes of the leading order terms.", "revisions": [ { "version": "v1", "updated": "2005-12-23T18:27:47.000Z" } ], "analyses": { "keywords": [ "one-dimensional directed sandpile models", "dependent random variables", "central limit theorem", "steady state properties", "totally asymmetric oslo model" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics A Mathematical General", "year": 2006, "month": "Jul", "volume": 39, "number": 29, "pages": 9107 }, "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006JPhA...39.9107S" } } }
