Comparison of CDW and nematicity dynamics. (A) CDW translational-symmetry breaking dynamics and (B) nematic rotational-symmetry breaking dynamics measured at $Q_{\text{CDW}}=(0.2601.74)$ and $Q=(001)$, respectively. Both datasets were taken at 20 K using probe photons resonant to the Cu $L_3$ resonance. (C) Schematic depiction of CDW degradation via amplitude suppression or the combination of amplitude suppression and topological defect formation.
