Abstract

In quasi-1D conducting nanowires spin-orbit coupling destructs spin-charge separation, intrinsic to Tomonaga-Luttinger liquid (TLL). We study renormalization of a single scattering impurity in a such liquid. Performing bosonization of low-energy excitations and exploiting perturbative renormalization analysis we extend the phase portrait in-space, obtained previously for TLL with decoupled spin-charge channels.

摘要

在准一维导电纳米线中，自旋轨道耦合破坏了汤川-卢廷格液体（TLL）固有的自旋-电荷分离。我们研究了这种液体中单个散射杂质的重整化。通过对低能激发进行玻色化并利用微扰重整化分析，我们扩展了先前在自旋-电荷通道解耦的TLL中获得的相空间图。
