Emergence of Discrete Spacetime Structure from Quantum Network Dynamics

Abstract

We explore a hypothesis in which a low-energy, approximately continuous spacetime descriptionemerges from quantum dynamics on an underlying discrete network. Starting from an abstractgraph with finite-dimensional quantum degrees of freedom on vertices and edges, we outline conditionsunder which correlation and entanglement patterns can support effective notions of distance,locality, and smooth geometry. We further discuss how gauge symmetries underlying the StandardModel—SU(3)c × SU(2)L × U(1)Y —may be interpreted as arising from internal structureand connectivity properties of the network. A characteristic discreteness scale ΛN = O(102 GeV)is introduced to parameterize leading departures from continuum field theory. The proximity ofΛN to the electroweak scale suggests a deep structural connection. We discuss potential observablesignatures and outline connections to phenomenological applications developed in companionpapers.
