论文摘要
考虑了在重型阻尼下周期性电势中球形活性布朗颗粒的转运性能。自属性粒子受到不对称电势，详细的平衡丢失，颗粒会产生非零的漂移速度。 计算平均电流，并根据有效扩散系数分析粒子的扩散率。对于手性活性颗粒，扩散率随着角速度的增加而降低，将粒子限制在初始位置附近，并降低平均电流。
The transport properties of a spherical active Brownian particle in a periodic potential under heavy damping are considered. The self-propelled particle is subjected to the asymmetric potential, detailed balance is lost and the particles generate a non-zero drift speed. The average current is calculated and the diffusivity of the particle is analyzed from the effective diffusion coefficient. For chiral active particles, the diffusivity decreases with increasing the angular velocity, confining the particle near the initial position, and reducing the average current.
