我们研究了弱相互作用一维电子系统的输运性质，包括由于三粒子碰撞和大尺度不均匀性的影响，在平等的基础上的热平衡。我们表明，在一个非均匀的量子线的平衡的特点是相互作用过程的竞争，减少电子的总动量和这样的改变的数量的右和左移动的电子。我们发现，相互作用和不均匀性的组合效应可以显着增加的电阻的线。此外，我们发现，相互作用强烈影响的热电性能的非均匀线，并计算其热导，热电势，和珀尔帖系数。
We study transport properties of weakly interacting one-dimensional electron systems including on an equal footing thermal equilibration due to three-particle collisions and the effects of large-scale inhomogeneities. We show that equilibration in an inhomogeneous quantum wire is characterized by the competition of interaction processes which reduce the electrons total momentum and such which change the number of right- and left-moving electrons. We find that the combined effect of interactions and inhomogeneities can dramatically increase the resistance of the wire. In addition, we find that the interactions strongly affect the thermoelectric properties of inhomogeneous wires and calculate their thermal conductance, thermopower, and Peltier coefficient.
