摘要翻译:
我们研究了有限温度下的周期驱动(对称和非对称)双阱势系统。我们发现,在外加场的每个周期内,系统对环境(浴)的平均热损失是随机共振的一个很好的量词。发现单周期内的热涨落总是大于功涨落。观测到的功和热分布在共振附近表现出明显的不对称性。在大量周期内的热损失满足常规的稳态涨落定理,但对于该量存在不同的关系。

英文摘要:
We study a periodically driven (symmetric as well as asymmetric)double-well potential system at finite temperature. We show that mean heat loss by the system to the environment(bath) per period of the applied field is a good quantifier of stochastic resonance. It is found that the heat fluctuations over a single period are always larger than the work fluctuations. The observed distributions of work and heat exhibit pronounced asymmetry near resonance. The heat losses over a large number of periods satisfies the conventional steady-state fluctuation theorem, though different relation exists for this quantity.
