a–d, Temperature-dependent 1/T1T in the triple-Q CDW phase. The 1/T1T was measured on the low-frequency peak of the central transition lines (see Fig. 2a). The nematic transition leads to an additional drop in 1/T1T below Tnem54. With increasing pressure, Tnem is nearly unchanged up to 0.48 GPa. The coloured line is a guide for the eyes. The grey vertical line marks Tnem. e–h, The evolution of the full width at half maximum (FWHM) in the triple-Q CDW phase. The FWHM was also measured on the low-frequency peak of the central transition lines. Similar to 1/T1T, a sudden increase in FWHM is also revealed below Tnem9. The black dashed line is a guide for the eyes. 1/T1T data for 0 GPa come from ref. 33. One of FWHM data for 0 GPa comes from ref. 9. Except for data for 0.08 GPa is measured on sample B, and data for other pressures are measured on sample A.
