Two prototypical dimers in the linear regime are investigated: a system of coupled classical oscillators, and a Schr\\\"{o}dinger dimer representing the coupling of field amplitudes; each system representing a wide class of physical models. Through a thorough analysis of their stability behaviour, we find that turning on the coupling parameter in the classical dimer system, leads initially to decreased sta","authors_text":"Demetra Psiachos, G.P.
