Dragging a Charge-Density-Wave Soliton by an Electromagnetic or Acoustic Wave

Research output: Contribution to journalArticlepeer-review

Abstract

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).
