双稳态束缚势中的随机共振。论禁闭的作用

Stochastic resonance in bistable confining potentials. On the role of confinement

Els Heinsalu, Marco Patriarca, Fabio Marchesoni

摘要:

研究了约束条件对连续双稳态系统中随机共振发生的影响。我们通过双阱势来模拟这样的系统,当|x|变为无穷大时,双阱势像|x|的q次方那样发散。对于q > 2的超谐波(硬)电势,SR峰随着q的增加而锐化,而对于q < 2的次谐波(软)电势,SR峰被抑制。

英文摘要:

We study the effects of the confining conditions on the occurrence of stochastic resonance (SR) in continuous bistable systems. We model such systems by means of double-well potentials that diverge like the q-th power of |x| when |x| goes to infinite. For super-harmonic (hard) potentials with q > 2 the SR peak sharpens with increasing q, whereas for sub-harmonic (soft) potentials, q < 2, it gets suppressed.
