论文摘要
在低温下，由于无序和相互作用的复杂相互作用，无序电子气体中的转运系数获得了量子校正。电导率的相互作用校正在虚拟过程中起源于典型的电子能，远远超过温度。在这里，我们研究了与远距离库仑相互作用的二维电子气体的热电$ s $ $ΔS$的交互校正$ΔS$。我们表明，尽管真实过程和虚拟过程都会有助于这些校正，但实际过程占主导地位，并导致对数温度依赖性$ΔS/s $，$ΔS/s <0 $。
At low temperatures, the transport coefficients in the disordered electron gas acquire quantum corrections as a result of the complex interplay of disorder and interactions. The interaction corrections to the electric conductivity have their origin in virtual processes with typical electronic energies far exceeding the temperature. Here, we study interaction corrections $δS$ to the thermopower $S$ of the two-dimensional disordered electron gas with long-range Coulomb interactions. We show that while both real and virtual processes contribute to these corrections, the real processes are dominant and lead to a logarithmic temperature dependence of $δS/S$ with $δS/S<0$.
