We consider the Ising model on a dense Erdős–Rényi random graph, $${\mathcal {G}}(N,p)$$G(N,p), with $$p>0$$p>0 fixed—equivalently, a disordered Curie–Weiss Ising model with $$\hbox {Ber}(p)$$Ber(p) couplings—at zero temperature. The disorder may induce local energy minima in addition to the two uniform ground states. In this paper we prove that, starting from a typical initial configuration, the zero-temperature dynamics avoids all such local minima and absorbs into a predetermined one of the… Expand

Local Minima in Disordered Mean-Field Ferromagnets
We consider the complexity of random ferromagnetic landscapes on the hypercube $$\{\pm \,1\}^N$$ { ± 1 } N given by Ising models on the complete graph with i.i.d. non-negative edge-weights. ThisExpand
Nature Versus Nurture: Dynamical Evolution in Disordered Ising Ferromagnets
We study the predictability of zero-temperature Glauber dynamics in various models of disordered ferromagnets. This is analyzed using two independent dynamical realizations with the same randomExpand

Friendly bisections of random graphs
Resolving a conjecture of Füredi from 1988, we prove that with high probability, the random graph G(n, 1/2) admits a friendly bisection of its vertex set, i.e., a partition of its vertex set into twoExpand
Stable and Metastable Phases for the Curie–Weiss–Potts Model in Vector-Valued Fields via Singularity Theory
We study the metastable minima of the Curie-Weiss Potts model with three states, as a function of the inverse temperature, and for arbitrary vector-valued external fields. Extending the classic workExpand

Long-time predictability in disordered spin systems following a deep quench.
It is conjecture that the influence of the initial state on the final state decays to zero in finite-dimensional random-bond spin systems as dimension goes to infinity, regardless of the presence of frustration. Expand
Extremal Cuts of Sparse Random Graphs
