非高斯非热涨落引起的热传导

Heat conduction induced by non-Gaussian athermal fluctuations

Kiyoshi Kanazawa, Takahiro Sagawa, Hisao Hayakawa

摘要:

研究了非高斯噪声在非热环境中诱导的热传导特性。我们发现,新的条款应添加到传统的傅立叶定律和波动定理的热流,它的平均值和波动不仅取决于噪声强度,但也由噪声的非高斯性质。我们的结果明确地表明,在无热系统中不存在热力学第零定律。

英文摘要:

We study the properties of heat conduction induced by non-Gaussian noises from athermal environments. We find that new terms should be added to the conventional Fourier law and the fluctuation theorem for the heat current, where its average and fluctuation are determined not only by the noise intensities but also by the non-Gaussian nature of the noises. Our results explicitly show the absence of the zeroth law of thermodynamics in athermal systems.
