论文摘要
跑步的颗粒,模仿大肠杆菌等微生物的行为,是活性物质的范式模型。由于自我推测,它们的随机运动和无向运动可以在棘轮潜力中纠正。使用扰动场理论,我们确定产生最大粒子电流作为粒子参数函数的电势的形状。
Run-and-Tumble particles, mimicking the behaviour of microorganisms like E. coli, are a paradigmatic model of active matter. Due to self-propulsion, their random and undirected motion can be rectified in a ratchet potential. Using perturbative field theory, we determine the shape of the potential that produces the maximum particle current as a function of the particles' parameters.
