Ultrafast dynamics in (TaSe${}_4$)${}_2$I triggered by valence and core-level excitation

Wibke Bronsch, Manuel Tuniz, Giuseppe Crupi +16

In this work, we study the out-of-equilibrium dynamics of the paradigmatic quasi-one-dimensional material (TaSe${}_4$)${}_2$I, that exhibits a transition into an incommensurate CDW pha…
