(color online) Three types of translational collective motion pattern. (a) An example of hopping motion pattern (RHX phase of ζ = 0.8 at η = 0.73) characterized by and P_d(r,t) ≡ G_d(r,t)/ρ. An example of a hopping trajectory is shown in black circle inset (different color represents different particle); (b)–(d) Snapshots of a representative trajectory at 3 different times t = 0.5 × 10⁴ (b), 2.5 × 10⁴ (c), and 3.5 × 10⁴ (d). (e) An example of gliding motion pattern (T phase of ζ = 0.09 at η = 0.79) characterized by P_s(r,t) ≡ 2πrG_s (r,t) and P_d(r,t). An example of a gliding motion is shown in black circle inset (different color represents different particle); (f)–(h) Snapshots of a representative trajectory at t = 0.3 × 10⁴ (f), 1.0 × 10⁴ (g), and 3.0 × 10⁴ (h). (i) An example of a mixture of hopping and gliding motion pattern (H phase of ζ = 0.5 at η = 0.73) characterized by P_s(r,t) and P_d(r,t). (j)–(l) Snapshots of a representative trajectory at t = 0.5 × 10⁴ (j), 2.5 × 10⁴ (k), and 3.5 × 10⁴ (l). The color code of each trajectory is determined based on the maximum displacement of the corresponding particle in a given time.
