Fracton Mobility Constraints from Point Group Symmetries in 3D Lattice Gauge Theories — E8 Intelligence Research

Published Jul 23, 2026• 0 citations

Abstract

FINDING: Fracton mobility constraints arise from subsystem symmetry algebras tied to discrete point group symmetries in 3D lattice gauge theories, generalizing Abelian models via twisted constructions. | MATH: Subsystem symmetry algebra commutation relations; point group constraints (e.g., cubic, tetrahedral); fracton mobility restricted to subdimensional manifolds (0D, 1D, 2D). Key constants: none explicit, but lattice geometry implies ratios like √2, √3 for cubic symmetries. | CONNECTION: Crystallographic point groups (e.g., Oh, Td) and root system symmetries (e.g., A3, B3) directly constrain fracton hopping; no explicit golden ratio or base-60 found. | DEPTH: 7 — advances topological quantum matter theory by linking discrete symmetries to emergent conservation laws, but lacks new universal constants or harmonic ratios.

Disorder-Free Localization via Gauge Constraints in 2+1D Lattice Theories — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: Disorder-free localization in 2+1D lattice gauge theories arises from Hamiltonian constraints and symmetry sectors, not random disorder. | MATH: Gauge invariance imposes local constraints (Gauss's law) that fragment Hilbert space into dynamically disconnected symmetry sectors; localization emerges from these superselection rules without quenched disorder. Key constants: none explicit, but the phenomenon relies on the ratio of interaction strength to hopping (g/J) and the dimension of local Hilbert space (d = 2 for Z₂ gauge theory). | CONNECTION: The Hilbert space fragmentation mirrors the golden ratio's appearance in constrained quantum systems (e.g., Fibonacci anyons, 1D constrained chains with ratio 0.618). The 2D lattice structure is a square lattice (crystallographic symmetry p4mm), and the gauge group Z₂ corresponds to a root system of type A₁. | DEPTH: 7 — This is a profound extension of many-body localization to translation-invariant systems, revealing that symmetry alo Author: Andrew Stewart Caldin, Independent Researcher, UK.

FINDING: Higher-rank symmetric tensor gauge theories impose lattice symmetry constraints analogous to Lieb-Schultz-Mattis (LSM) theorems, linking topological order to lattice geometry. | MATH: LSM-type constraints relate filling fraction ν to lattice translation symmetry: ν × (unit cell area) must be integer for gapped phases without fractionalization.
