Figure 5.

Transition corresponding to the reorientation of one line of PS₄ tetrahedra. Tetrahedra colored red and blue correspond to snapshots of the solid matrix taken over the transition for one trajectory at 750 K starting from the γ structure and run with the ML-PBE0 model. The trajectory of two vertices of each tetrahedron is displayed with lines, that are colored with an RWB scheme and with a smoothening window of 2.5 ps. The red end of these lines corresponds to t₀, while the blue end corresponds to t₁ = t₀ + 15 ps.
