particlessuch

Particlessuch is a term used in speculative discussions of quantum theory and the philosophy of science to denote a class of particle-like excitations that do not maintain a fixed identity. In this conception, what counts as a particle is determined by relational properties within a system, rather than by intrinsic attributes. Consequently, such entities are defined by their interactions and context rather than by persistent characteristics like mass or charge, making their individuality contingent rather than intrinsic.

The term arose in theoretical debates about the ontology of quantum fields and many-body systems, where emergent phenomena blur the line between objects and states. It is not tied to a single model but describes a family of approaches that treat localization and individuality as emergent and context-dependent rather than as fundamental traits.

Within these frameworks, particlessuch excitations may appear as localized collective modes or relational states encoded in entanglement patterns. They can propagate and interact as if they were particles in an effective theory, yet they lack a fixed, intrinsic identity that survives arbitrary transformations of the system. Their properties are described by the governing theory’s relational variables rather than a stable set of quantum numbers.

Particlessuch concepts are used to explore questions about identity in quantum systems, the ontology of fields, and the limits of particle-centric descriptions. They are often compared with quasi-particles or gauge excitations to highlight how apparent individuality can be an emergent feature of a given theoretical framework.

Scholars note that particlessuch provide a useful heuristic for thinking about ontology and emergence, while some criticize the notion as vague or model-dependent.
