约束对连续双稳态系统随机共振的影响

The effect of confinement on stochastic resonance in continuous bistable systems

Shubhashis Rana, Sourabh Lahiri, A. M. Jayannavar

摘要:

使用输入能量作为量化的随机共振(SR),我们发现,SR观察超谐波(硬)势。然而,在次谐波(软)势中没有观察到,即使势是双稳态。这些结果与最近基于平均位置幅度作为量词的观察结果是一致的。在软势和硬势中,我们观察到共振现象作为驱动频率的函数。软势和硬势的平均功的概率分布性质是不同的。

英文摘要:

Using the input energy per cycle as a quantifier of stochastic resonance (SR), we show that SR is observed in superharmonic (hard) potentials. However, it is not observed in subharmonic (soft) potentials, even though the potential is bistable. These results are consistent with recent observations based on amplitude of average position as a quantifier. In both soft and hard potentials, we observe resonance phenomenon as a function of the driving frequency. The nature of probability distributions of average work are qualitatively different for soft and hard potentials.
