Bootstrap percolation and the Ising model
Abstract
Glauber dynamics on $\mathbb{Z}^d$ is a dynamic representation of the zero-temperature Ising model, in which the spin (either $+$ or $-$) of each vertex updates, at random times, to the state of the majority of its neighbours. It has long been conjectured that the critical probability $p_c(\mathbb{Z}^d)$ for fixation (every vertex eventually in the same state) is $1/2$, but it was only recently proved (by Fontes, Schonmann and Sidoravicius) that $p_c(\mathbb{Z}^d)

Using Spin to Distinguish Models at the LHC
Abstract
If new particles are produced at the LHC, it is vital that we can extract as much information as possible from them about the underlying theory. I will discuss some recent work on extracting spin information from invariant mass distributions of new particles. I will then introduce the Kullback-Leibler method of quantifying our ability to distinguish different scenarios.
