Suppression of axionic charge density wave and onset of superconductivity in the chiral Weyl semimetal Ta${}_2$Se${}_8$I

Qing-Ge Mu, Dennis Nenno, Yan-Peng Qi +7

A Weyl semimetal with strong electron-phonon interaction can show axionic coupling in its insulator state at low temperatures, owing to the formation of a charge density wave (CDW)…
