On the Conceptual Issues Surrounding the Notion of Relational Bohmian Dynamics

Abstract: The paper presents a program to construct a non-relativistic relational Bohmian theory, that is, a theory of N moving point-like particles that dispenses with space and time as fundamental background structures. The relational program proposed is based on the bestmatching framework originally developed by Julian Barbour. In particular, the paper focuses on the conceptual problems that arise when trying to implement such a program. It is argued that pursuing a relational strategy in the Bohmian context leads to… Show more

“…In this regard, it may be useful to focus on a particular quantum theory that shares with PSD the fundamental role accorded to instantaneous spatial configurations. The most promising candidate to this role is the de Broglie-Bohm theory, which has been recently shown to be amenable to the quotienting out procedure discussed in §1 (Vassallo and Ip, 2016;Dürr et al, 2020). Nonetheless, the details of this construction still require much work-as does the extension to quantum field theory-and will be the subject of our future investigations.…”

“…where ∆ B and ∇ B are, respectively, the Laplace-Beltrami operator and the gradient on the configuration space equipped with respect to the Riemannian metric (4). This is all there is to say about the formulation of Bohmian mechanics on shape space (this should perhaps be contrasted with more involved approaches as in, e.g., [21]).…”

“…The geometry and the time with its metric can be conceived as a mere means to represent the particle configuration and its change, that is, the change in the relative distances of the particles (see Esfeld and Deckert (2017, ch. 3.2) for the philosophical argument and Vassallo and Ip (2016) for a relationalist formulation of BM). Consequently, the particles are individuals that are absolutely discernible by their position in a configuration.…”
