Optically induced changes in the band structure of the Weyl charge-density-wave compound

Optically induced changes in the band structure of the Weyl charge-density-wave compound

Collective modes are responsible for the emergence of novel quantum phases in topological materials. In the quasi-one dimensional (1D) Weyl semimetal $(\mathrm{TaSe}_4)_2\mathrm{I}$ , a charge density wave (CDW) opens band gaps at the Weyl points, thus turning the system into an axionic insulator. M...
