We study the Ising p-spin glass model for large p. We 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 \(n\rightarrow \infty \) , 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 glass models. Furthermore, 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 \(\gamma \sqrt{2\ln 2}\) . Our proofs are elementary, and in particular based on simple applications of the first and the second moment methods.
