结构性噪声引起的非再交叉势垒逃逸
Structured noise induced non-recross barrier escaping
摘要：
在亚稳势场中，研究了结构噪声驱动下粒子随时间的势垒通过。计算了逃逸率的传递系数和越过鞍点的概率等参数，对扩散动力学性质有了一定的了解。结果表明，结构化噪声环境大大降低了障碍物的再穿越行为。在这种耗散环境中，粒子的扩散往往会成功地从势阱中逃逸出来，而不会产生任何阻碍。
英文摘要：
The time-dependent barrier passage of a particle driven by the structured noise is studied in the field of a metastable potential. Quantities such as the probability of passing over the saddle point and transmission coefficient of the escaping rate are calculated for a thimbleful of insight into the diffusion dynamical properties. Results show that the barrier recrossing behavior is greatly reduced by the structured noisy environment. Particles diffusion in such an dissipative environment tends to successfully escape from the potential well without any embarrassments.
