论文摘要
跑步运动是主动运动的一个示例,其中粒子以恒定速度移动并在随机时间改变方向。在这项工作中,我们通过路径积分方法在一个维度中以谐波电位扩散在谐波电位中进行跑步运动。我们得出了一个doi-peliti场理论,并以封闭形式计算熵产生和其他可观察物。我们所有的结果都是准确的。
Run-and-tumble motion is an example of active motility where particles move at constant speed and change direction at random times. In this work we study run-and-tumble motion with diffusion in a harmonic potential in one dimension via a path integral approach. We derive a Doi-Peliti field theory and use it to calculate the entropy production and other observables in closed form. All our results are exact.
