Abstract

The expression for the conductance of a 1D channel, which has been obtained using the well-known exact solution, is analyzed. It is shown that in the case of strong electron—electron interaction, the slowest (linear in frequency) asymptotics of the conductance is determined by the behavior of electron—electron interaction in the region of transition from 1D to 3D motion realized near the impurity.

具有排斥和单点杂质的Luttinger液体的精确解

分析了使用众所周知的精确解获得的一维通道电导的表达式。结果表明，在强电子-电子相互作用的情况下，电导的最慢（频率上的线性）渐近线由杂质附近实现的从1D到3D运动的过渡区域中的电子-电子交互作用的行为决定。
