A quantum-like model of political consensus via non self-adjoint Hamiltonians

We discuss here how non self-adjoint Hamiltonians, and their related Heisenberg-like dynamics, can be used to model a political system consisting in a coalition $\text{C}$ of different parties (forming a government) and by their (original) supporters $\text{Sc}$. Our aim is to model how the opinion of these supporters changes depending on the efficiency, competence and coherence of the coalition $\text{C}$, as these are perceived by $\text{Sc}$ during their action while governing. After a rather general introduction we propose three specific models, and we describe and comment the dynamical behaviour of the { full} system, $\text{Sc}\cup \text{C}$. The role of the so-called {\em balanced Hamiltonians}, recently introduced by the authors in connection with integrals of motion, is discussed in details.
