Title: Mutual information disentangles interactions from changing environments
(Submitted on 19 Jul 2021 (v1), last revised 20 Oct 2021 (this version, v2))
Abstract: Real-world systems are characterized by complex interactions of their internal degrees of freedom, while living in ever-changing environments whose net effect is to act as additional couplings. Here, we introduce a paradigmatic interacting model in a switching, but unobserved, environment. We show that the limiting properties of the mutual information of the system allow for a disentangling of these two sources of couplings. Further, our approach might stand as a general method to discriminate complex internal interactions from equally complex changing environments.
