研究表明，传播的电磁波或声波以与波振幅的平方成正比的速度在几乎相称的CDW导体中拖曳相位孤立子。在含有“冻结”单极孤子的导体中，带电孤子的行波诱导漂移引起特定的光电（实际上是无线电）和声电效应。这些效应可以用来间接检测CDW孤子，并估计它们的大小（驱动波的截止波长与孤子的特征大小一致）。
It is demonstrated that a traveling electromagnetic or acoustic wave drags a phase soliton in a nearly commensurated CDW conductor at a velocity proportional to the square of the wave's amplitude. The traveling-wave-induced drift of the charged soliton gives rise to specific photoelectric (actually, radioelectric) and acoustoelectric effects in the conductor containing “frozen” unipolar solitons. These effects can be used to indirectly detect the CDW solitons, and to estimate their size (the cutoff wavelength of the driving wave coincides with a characteristic size of the soliton).
