Classicity from Entangled Ensemble States of Knotted Spin Networks. A Conceptual Approach

TL;DR

This paper proposes a conceptual framework where classicality emerges from entangled, knotted spin network states, suggesting that fundamental physics is non-local and non-temporal, challenging traditional causal notions.

Contribution

It introduces a novel conceptual approach linking entangled ensemble states of knotted spin networks to the emergence of classical physics, emphasizing non-locality and non-temporality.

Findings

Classicality can be visualized as emerging from entangled knotted spin networks.

Physics at the fundamental level is non-local and a-temporal, lacking traditional causality.

Spin foam models are compatible with non-causal, non-temporal fundamental structures.

Abstract

Referring to a conception put forward by Stuart Kauffman in his "Investigations", it is shown how the onset of classicity can be visualized in terms of an emergent process originating in entangled ensemble states of knotted spin networks. The latter exhibit a suitable autocatalytic behaviour effectively producing knots by knots acting upon other knots. In particular, a quantum computational structure can be described underlying spin networks such that most conditions for a partial ordering are not more valid for the latter. A concep- tual argument is given then indicating that on a fundamental level, physics is non-local and a-temporal, and hence does not admit of the concept of causality. Hence, modelling the emergence of classicity in terms of a percolating web of coherence eventually decohering (in using a cellular automata architecture) does not imply the necessity of visualizing histories of directed percolation as causal sets. These aspects are compatible though with the recent concept of spin foams which do not actually imply distinguished directions of time flow on the micro-level.
