Spherical harmonics gradient
WebApr 13, 2024 · A. State diagram in the χ – λ plane. Figure 3 depicts the hydrodynamic behavior of two chiral swimmers in the presence of an external chemical gradient. When λ 1 = λ 2 = λ and χ 1 = χ 2 = χ, the swimmers are identical (see Fig. 3 caption). The swimmers portray various behaviors for varying λ / v and χ.
