CDW Gap Collapse and Weyl State Restoration in Ta${}_2$Se${}_8$I via Coherent Phonons: A First-Principles Study

Tao Jiang, Jigang Wang, Yong-Xin Yao

Coherent phonon excitation offers a nonthermal route to control quantum phases of condensed matter. In this work, we employ first-principles calculations to investigate the phonon…
