Proxies for the variation of order parameters with symmetry and Δ5, each scaled to Q = 1 at 0 K. The average and individual symmetry-adapted displacements do not depend on the same order parameter components as the shear strains but all three sets of data show the same pattern of evolution: a large discontinuity in the electronic and cation charge order components of the transition at Tv (broken line) is followed by small variations predominantly in the cation charge order component with further reduction in temperature. |
