Abstract Since Galileo, physics has traditionally adopted a closed-system view, framed in the more generic strategy of describing highly idealized and generally non-existent situations. However, in the field of quantum mechanics—and also in other fields of physics—an open-system view has been gaining strength in recent decades, maybe under the influence of the practical success of the environment-induced decoherence (EID) developments. This trend is at odds with the perspective of the MHI, which openly adopts a closed-system view. The aim of this chapter is to discuss several aspects of quantum mechanics that reveal the difficulties faced by an open-systems approach. On this basis, a case is made for a closed-system approach that leads to a top-down view of quantum mechanics. This top-down view is in agreement with the ontology of properties introduced in Chapter 4, which will be developed in detail in the following Chapters 9, 10, and 11.

The study of quantum mechanics in non-inertial reference frames, particularly in the context of open systems, introduces several intriguing phenomena and challenges. This paper presents a comprehensive framework for analyzing the quantum mechanics of open systems undergoing noninertial motion. Our methodology leverages the concept of dissipatons, statistical quasi-particles that capture collective dissipative effects from the environment. We demonstrate that our approach offers a natural understanding of the intricate dynamics among non-inertial effects, decoherence, dissipation, and system-bath entanglement. Specifically, we conduct demonstrations focusing on the Lamb shift phenomenon within a rotating ring cavity. Through theoretical exposition and practical applications, our framework elucidates the profound interplay between open quantum dynamics and non-inertial motion, paving the way for advancements in quantum information processing and sensing technologies.
