We consider the interplay of the elastic pinning and the Anderson localization in the transport properties of a charge-density wave in one dimension, within the framework of the Luttinger model in the limit of strong repulsion. We address a conceptually important issue of which of the two disorder-induced phenomena limits the mobility more effectively. We argue that the interplay of the classical and quantum effects in transport of a very rigid charge-density wave is quite nontrivial: the quantum localization sets in at a temperature much smaller than the pinning temperature, whereas the quantum localization length is much smaller than the pinning length.
在强排斥极限下的卢廷格模型框架内，我们考虑了一维电荷密度波输运性质中弹性钉扎与安德森局域化的相互作用。我们探讨了一个概念上重要的问题，即两种无序诱导现象中哪一种更有效地限制了迁移率。我们认为，在非常刚性的电荷密度波输运中，经典效应与量子效应的相互作用相当复杂：量子局域化在远低于钉扎温度的温度下出现，而量子局域化长度远小于钉扎长度。
