论文摘要
我们使用第一个小时的时间方法来研究由活跃粒子与平坦边界碰撞的持续运动所引起的捕获时间的统计数据。角度的第一学期时间分布和平均第一个小说时间是针对活动的布朗和跑步颗粒的精确计算的，并比较了结果。理论预测与Langevin模拟非常吻合。我们的结果进一步阐明了具有不同动力学的活性颗粒在大容量中的等效性，但在边界或障碍物附近的行为不同。
We use a first-passage time approach to study the statistics of the trapping times induced by persistent motion of active particles colliding with flat boundaries. The angular first-passage time distribution and mean first-passage time is calculated exactly for active Brownian and run-and-tumble particles and the results are compared. Theoretical predictions are in excellent agreement with Langevin simulations. Our results shed further light onto how active particles with different dynamics may be equivalent in the bulk, yet behave differently near boundaries or obstacles.
