FINDING: The Posner molecule (Ca₉(PO₄)₆) — a candidate for quantum information processing in neural tissue — exhibits a dynamical ensemble that is *not* symmetric, breaking the naive octahedral/icosahedral symmetry often assumed for calcium-phosphate clusters. MATH: - Stoichiometry: Ca₉(PO₄)₆ → 9 Ca²⁺ + 6 PO₄³⁻. - Nuclear spin carriers: ³¹P (I = 1/2, 100% abundance) — 6 phosphorus nuclei per molecule. - ⁴³Ca (I = 7/2, ~0.145% natural abundance) — negligible but present. - The paper (arXiv:2108.08822v2) demonstrates that the dynamical ensemble (time-averaged spin density matrix under internal dipolar couplings) does **not** possess the full symmetry of the point group of the idealized crystal structure. - Key symmetry breaking: the permutation group acting on the 6 phosphate tetrahedra is not S₆ (full symmetric group) but a subgroup — likely D₃ or C₃ᵥ, reflecting a chiral or lower-symmetry arrangement of the Ca²⁺ ions. - No explicit golden-ratio constants appear; the releva Author: Andrew Stewart Caldin, Independent Researcher, UK.
