Non-Gaussianity-induced Heat Conduction    [PDF]

Kiyoshi Kanazawa, Takahiro Sagawa, Hisao Hayakawa
We study the properties of a Brownian motor that is driven 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 result explicitly shows the absence of the zeroth law of thermodynamics in athermal systems.
