Typical patterns of the coarse-grained site dipoles and vorticities found in the MD simulation (i). (A) Instantaneous site dipoles, d̄(r_i,R,t), coarse grained with sphere of R = 3L_cube at an exemplified instance t. Vectors with length |d̄| ≥ 0.8 × |d̄_max| are shown by bars. (B) Time-averaged site dipoles over the duration w = 300 ps, d̄_w(r_i,R), coarse grained with R = 2L_cube. Vectors with length |d̄_w| ≥ 0.45 × |d̄_w,max| are shown by bars. (C) Vorticity of the instantaneous site dipoles, v(r_i,R,t), calculated with the sphere of R = 6L_cube at the same instance t as in A. Vectors with length |v| ≥ 0.6 × |v_max| are shown by bars. (D) Vorticity of the time-averaged site dipoles over 300 ps, v_w(r_i,R), calculated with R = 6L_cube. Vectors with length |v_w| ≥ 0.55 × |v_w,max| are shown by bars.
