We show that for any $\\gamma>0$ and any large enough $p$, the model exhibits an intricate geometrical property known as the multi Overlap Gap Property above the energy value $\\gamma\\sqrt{2\\ln 2}$. We then show that for any inverse temperature $\\sqrt{\\ln 2}<\\beta<\\sqrt{2\\ln 2}$ and any large $p$, the model exhibits shattering: w.h.p. as $n\\to\\infty$, there exists exponentially many well-separated clusters such that (a) each cluster has exponentially small Gibbs mass, and (b) the clusters collectively contain all but a vanishing fraction of Gibbs mass. Moreover, these clusters consist of configurations with energy near $\\beta$. Range of temperatures for which shattering occurs is within the replica symmetric region. To the best of our knowledge, this is the first shattering result regarding the Ising $p$-spin models. Our proof is elementary, and in particular based on simple applications of the first and the second moment methods.", "revisions": [ { "version": "v1", "updated": "2023-07-14T16:43:18.000Z" } ], "analyses": { "keywords": [ "spin model", "ising pure", "shattering", "multi overlap gap property", "replica symmetric region" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
