Abstract

An incommensurate CDW may have the ability to slide, i.e., to generate an excess of current when the system is submitted to an external field. Sliding phenomenon is closely related to deformation of the periodic lattice distortion associated to the CDW. In principle, however, the sliding state can also be observed through the band structure. Here we show that broken symmetry in k-space is observed by Angle-Resolved Photoemission Spectroscopy (ARPES) in the sliding regime of TbTe $_3$ , which could be consistent with theoretical predictions.
