Asymmetric Nuclear Spin Dynamics in Posner Molecules — E8 Intelligence Research
FINDING: The Posner molecule Ca₉(PO₄)₆ — a calcium-phosphate cluster implicated in quantum biological information processing — has a dynamical ensemble that is *not* symmetric, breaking the naive octahedral/cubic symmetry often assumed for its nuclear spin states. MATH: - Stoichiometry: Ca₉(PO₄)₆ → 9 Ca²⁺, 6 PO₄³⁻. - Nuclear spin carriers: ³¹P (I = 1/2), ⁴³Ca (I = 7/2), ¹⁷O (I = 5/2). - Key symmetry group (idealized): T_d or O_h for the phosphate tetrahedra, but the *dynamical* ensemble (rotational/vibrational + spin) reduces to a lower point group — likely C₁ or C₂ due to Jahn–Teller-like distortions and hydration. - Quantum information metric: coherence time τ_c ∝ (ΔE / ħ)⁻¹, where ΔE is the zero-field splitting of ³¹P–⁴³Ca coupled states. - The paper (arXiv:2108.08822v2) explicitly shows the ensemble average over molecular orientations does *not* preserve the full symmetry — the density matrix ρ_ensemble ≠ Σᵢ Rᵢ ρ Rᵢ† for all Rᵢ ∈ T_d.
