Description

We discuss the phenomenon of phase-ordering after a temperature quench in systems with long-range interactions decaying with distance $r$ as $r^{-\alpha}$, focusing mainly on the Ising model in $d=1$.
For $\alpha >d$ one observes formation and growth of ordered domains, with scaling exponents continuously depending on
$\alpha$. For $\alpha=0$ one has mean field, where the system coherently orders without domains formation. For $\alpha \le d$
there is an hybrid situation where both mean-field like and coarsening like behaviors are observed as different statistical realizations of the process are considered.
