Kipnis, Marchioro, and Presutti (KMP) introduced in 1980 a very simple Markovian model for energy exchange in a chain of harmonic oscillators. In many ways, the KMP model behaves like the symmetric simple exclusion process (SSEP). The goal of this talk is to explain why, unlike the SSEP, the KMP model converges to the Kardar-Parisi-Zhang (KPZ) equation under a somewhat unusual scaling. The proof r
