A Self-Interaction Leading to Fluctuations of Order $n^{5/6}$

Abstract

In arXiv:1301.6911, we built and studied a Curie-Weiss model exhibiting self-organized criticality : it is a model with a self-interaction leading to fluctuations of order $n^{3/4}$ and a limiting law proportional to $\exp (-x^4/12)$. In this paper we modify our model in order to "kill the term $x^4$" and to obtain a self-interaction leading to fluctuations of order $n^{5/6}$ and a limiting law $C\exp (-\lambda x^6)dx$, for suitable positive constants $C$ and $\lambda$.
