*“**Self-sustained clusters in spin glass models**”*



*Abstract:*

While macroscopic properties of spin glasses have been thoroughly
investigated, their manifestation in the corresponding microscopic
configurations is much less understood. To identify the emerging
microscopic structures with macroscopic phases at different temperatures,
we introduce the concept of self-sustained clusters (SSC). SSC are
regions of the space where in-cluster induced fields dominate over the
field induced by out-cluster spins. We study their properties in the
Ising p-spin model with p=3 using replicas. The intuition gained using
fully connected models is then used in the study of models defined on
random graphs. A message-passing algorithm is developed to determine the
probability of individual spins to belong to SSC. Results for specific
instances, which compare the predicted SSC associations with the dynamical
properties of the spins, are obtained from numerical simulations. This
insight gives rise to a way to predict individual spin dynamics from a
single snapshot of spin configurations.



Tutti gli interessati sono invitati a partecipare.
