The structure factor of the particle density behaves for small $q$ as $S(q)\\sim |q|^\\sigma$ with $\\sigma={4-d-2\\zeta}$, where $\\zeta$ is the roughness exponent at depinning. In dimension $d=1$, $\\sigma=1/2$, while for all dimensions $0.6> \\sigma\\ge0$. Our results fit well known simulations in the literature, except in $d=1$, where we perform our own simulations to confirm our findings.", "revisions": [ { "version": "v1", "updated": "2024-01-17T10:53:55.000Z" } ], "analyses": { "keywords": [ "conserved directed percolation", "manna model", "hyperuniformity", "particle density behaves", "results fit" ], "note": { "typesetting": "TeX", "pages": 3, "language": "en", "license": "arXiv", "status": "editable" } } }
