We study a vectorial version of the dynamical Phi4 model with N coupled components, known as the O(N) linear sigma model. We analyze the behavior for large N on the 2d torus. This leads to a mean-field singular SPDE which governs the limiting behavior in both equilibrium and non-equilibrium settings for sufficiently large mass. This is joint work with Hao Shen, Rongchan Zhu, and Xiangchan Zhu.
