非平衡电子系统温度涨落的统计

Statistics of temperature fluctuations in an electron system out of equilibrium

Tero T. Heikkila, Yuli Nazarov

摘要:

我们研究了波动的电子温度在一个金属岛耦合到水库通过电阻接触和驱动的平衡,无论是温度或电压差的水库之间的统计。温度的波动是很好地定义的,提供的能量弛豫率内的岛屿超过与水库的能量交换率。我们量化这些波动的制度超越高斯近似,并阐明其依赖于电子接触的性质。

英文摘要:

We study the statistics of the fluctuating electron temperature in a metallic island coupled to reservoirs via resistive contacts and driven out of equilibrium by either a temperature or voltage difference between the reservoirs. The fluctuations of temperature are well-defined provided that the energy relaxation rate inside the island exceeds the rate of energy exchange with the reservoirs. We quantify these fluctuations in the regime beyond the Gaussian approximation and elucidate their dependence on the nature of the electronic contacts.
