『Slow dynamics in systems with long-range interactions』
I will review several non-equilibrium dynamical effects
characteristic of systems with long-range interactions. In particular,
the intriguing formation of quasi-stationary states, which evolve to
equilibrium slower and slower as system size increases. In this
respect, I will discuss several models which show such features,
beginning with simple mean-field models of the Ising or the XY type.
