      Eyal Lubetzky (Microsoft Research)
 
and the title of his talk is
 
      The static and stochastic Ising models
 
The abstract is given below. Tea and coffee at 12:00, same room.
 
Hope to see you there. For information about past colloquiua, see

Abstract: The Ising model, one of the most studied models in
mathematical physics, was introduced in 1925 to model ferromagnetism.
In the classical 2D setting, the model assigns plus/minus spins to the
sites of the square grid according to a given probability
distribution, which is a function of the number of neighboring sites
whose spins agree, as well as the temperature. Over the last three
decades, significant effort has been dedicated to the analysis of
stochastic dynamical systems that both model the evolution of the
Ising model and provide efficient methods for sampling from it. In
this talk I will survey the rich interplay between the behaviors of
the static and the dynamical models as they both undergo a phase
transition at the critical temperature. In particular I will discuss a
fundamental problem on the dynamical model introduced by Glauber in
1963, which we recently settled in joint work with Allan Sly.
