(Left) The normalized thermal displacement vector $\mathcal{𝓧}$, defined in Eq. 2, measured in a model glass in 2D (details are in the text) of $N=1,600$ particles. (Right) A spatial map of the normalized LTE ${\mathcal{E}}_{\alpha }$, defined in Eq. 3, for the same glass realization shown in Left. Line thickness and opacity represent the LTE, with red (black) representing negative (positive) LTE.
