Published: Ultrafast all-optical manipulation of the charge-density wave in VTe2

We investigate the broadband time-resolved reflectivity variations caused by collective and single particle excitations in the CDW ground state of VTe2. With the aid of density functional perturbation theory (DFPT) simulations we unveil the presence of two collective amplitude modes of the CDW ground state.
