Eigenframe Curvature Scaling at Quantum Critical Points: Prediction and Test Protocol Using Existing CoNb₂O₆ NMR Data
Abstract
We predict eigenframe curvature κ scales as κ ~ Δ^(-α) near quantum critical points, with α = 1 for transverse field Ising chain universality. We identify that Kinross et al. (Phys. Rev. X 4, 031008, 2014) CoNb₂O₆ NMR data already contains the information to test this - their "weaker than expected" divergence is consistent with a gap-dependent prefactor encoding eigenframe curvature. This deposit establishes priority for the prediction and reanalysis protocol.
