The entanglement wedge cross section (EWCS) is numerically investigated statically and dynamically in a five-dimension AdS-Vaidya spacetime with Gauss-Bonnet (GB) corrections,focusing on two identical rectangular strips on the boundary.In the static case,EWCS increases as the GB coupling constant a increases and disentangles at small separation between two strips for smaller α.For the dynamic case,such a monotonic relationship between EWCS and a holds but the two strips no longer disentangle monotonically as in the static case.In the early thermal quenching stage,the disentanglement occurs at smaller α with larger separations.Two strips then disentangle at larger separation with larger α as time evolves.Our results indicate that the higher-order derivative corrections,like the entanglement measure in the dual boundary theory,also have nontrivial effects on the EWCS evolution.
