Inhibition of the photoinduced structural phase transition in the excitonic insulator Ta${}_2$NiSe${}_5$

Selene Mor, Marc Herzog, Johannes Noack +7

Femtosecond time-resolved mid-infrared reflectivity is used to investigate the electron and phonon dynamics occurring at the direct band gap of the excitonic insulator Ta${}_2$NiSe$_…
