Fig. 4: Simulation of 121Sb-NQR spectrum at P = 1.72 GPa.

From: Commensurate-to-incommensurate transition of charge-density-wave order and a possible quantum critical point in pressurized kagome metal CsV3Sb5

Fig. 4

a and b display the two possible CDW patterns with a one-dimensional (1D) incommensurate (IC) modulation, in which a represents the superimposed SoD and TrH pattern stacking along the c-axis and b represents the coexistence of SoD and TrH domains, respectively. d and e illustrate the superimposed two-dimensional (2D) incommensurate SoD and TrH pattern with an additional charge modulation along the a-axis and c-axis, respectively. The gray level represents the charge density. c and f show the comparison of the 121Sb-NQR spectra at P = 1.72 GPa (gray circle), the simulated incommensurate spectra (black dotted line) and the calculated convolution (orange area for TrH pattern and blue area for SoD pattern) for 1D and 2D incommensurate CDW modulations (details about NQR spectra simulation are present in Supplementary Note 5), respectively. The peaks corresponding to Sb1 and Sb2 sites are marked by the red dashed arrows.
