\({\Psi }_{{\rm{L}}}^{x}\) diverges at both Jo/Je = 1 and 2, where we observe the changes of signs for operators when crossing these two points. The solid boxes denote theoretical predictions, where black and red frames mark positive and negative values, respectively. The coefficients are obtained by averaging the late-time dynamics over cycles from t = 25 to 40, with the sum of their squares normalized to unity.
