滚转粒子的最优棘轮势

Optimal Ratchet Potentials for Run-and-Tumble particles

Zigan Zhen, Gunnar Pruessner

摘要:

奔跑翻滚的颗粒,模仿微生物的行为,如E。大肠杆菌是活性物质的典型模型。由于自推进,它们的随机和无向运动可以在棘轮电势中得到纠正。利用微扰场论,我们确定了产生最大粒子流的势的形状作为粒子参数的函数。

英文摘要:

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.
