Shattering in the Ising Pure -Spin Model

D Gamarnik, A Jagannath, EC Kızıldağ - arxiv preprint arxiv:2307.07461, 2023 - arxiv.org
We study the Ising pure $ p $-spin model for large $ p $. We investigate the landscape of the
Hamiltonian of this model. We show that for any $\gamma> 0$ and any large enough $ p …
