论文摘要
我们使用合并的实验，理论和数值方法研究了模型微观运动员（衣原体Reinhardtii）的随机力动力学。尽管使用流体动力学方法对游泳动力学进行了广泛的研究，从而从粘性流场推断力，但我们通过光子动量方法直接测量了微晶体器产生的随机力。我们通过将微磁化器作为一个自propell的粒子（一个活性物质）进行建模，并使用随机热力学的方法来分析力动力学。我们在$ 10^6 $ $ k_b t / s $（$ \ sim $ fw）的订单上找到复杂的振荡力动力学和功率耗散
We study the stochastic force dynamics of a model microswimmer (Chlamydomonas reinhardtii), using a combined experimental, theoretical, and numerical approach. While swimming dynamics have been extensively studied using hydrodynamic approaches, which infer forces from the viscous flow field, we directly measure the stochastic forces generated by the microswimmer using an optical trap via the photon momentum method. We analyze the force dynamics by modeling the microswimmer as a self-propelled particle, a la active matter, and analyze it's energetics using methods from stochastic thermodynamics. We find complex oscillatory force dynamics and power dissipation on the order of $10^6$ $k_B T / s$ ($\sim$ fW)
