Description
In this talk, I will discuss excursion decompositions in various models of statistical physics. By an excursion decomposition, we mean a representation of a field as a sum $\sum_n \mu_n \delta_n$, where the $\mu_n$ are positive measures with disjoint supports and the $\delta_n$ are i.i.d. fair signs. The models to be discussed are both the discrete and continuous versions of the random walk, Ising model, Gaussian free field and the XOR-Ising model.
This talk is based on joint work with Tomás Alcalde, Juhan Aru, and Titus Lupu
