论文摘要
我们通过修改的相互定理来得出线性粘弹性流体中活性颗粒的惯性动力学的一般公式。然后，我们证明了麦克斯韦（Maxwell）线性粘弹性流体中无力的活性颗粒，没有阻滞性具有与牛顿流体中完全相同的动力学。相比之下，具有阻滞性的杰弗里（Jeffreys）样流体中的活性颗粒可以显示出明显不同的动态，包括在相互驱动下的净运动，从而破坏扇贝定理。
We derive a general formula for the inertialess dynamics of active particles in linear viscoelastic fluids by means of a modified reciprocal theorem. We then demonstrate that force-free active particles in Maxwell-like linear viscoelastic fluids with no retardation have exactly the same dynamics as in Newtonian fluids. In contrast, active particles in Jeffreys-like fluids with retardation can display markedly different dynamics, including net motion under reciprocal actuation thereby breaking the scallop theorem.
