Coupled order parameters and photoinduced domain walls in the charge density wave of (TaSe4)2I

Abstract The charge density wave in (TaSe4)2I has drawn much attention recently as a controversial candidate for an axion insulator where the CDW breaks the chiral symmetry of the Weyl semimetal. Here we use ultrafast x-ray scattering to study the collective modes of this CDW. By measuring several d...
