关于热流的散粒噪声极限

On the shot-noise limit of a thermal current

Kelly R. Patton

摘要:

本文计算了两个不同温度的宏观电介质体之间的热流噪声功率谱密度。假设热能仅由声子携带,我们将量子点接触建模为具有谐波弹簧势的机械链接。在弱耦合,或弱链接限制,我们发现的热流模拟的著名的电子散粒噪声的表达。

英文摘要:

The noise power spectral density of a thermal current between two macroscopic dielectric bodies held at different temperatures and connected only at a quantum point contact is calculated. Assuming the thermal energy is carried only by phonons, we model the quantum point contact as a mechanical link, having a harmonic spring potential. In the weak coupling, or weak-link limit, we find the thermal current analog of the well-known electronic shot-noise expression.
