Author(s): Selene Mor, Marc Herzog, Johannes Noack, Naoyuki Katayama, Minoru Nohara, Hide Takagi, Annette Trunschke, Takashi Mizokawa, Claude Monney, and Julia Stähler Femtosecond time-resolved midinfrared reflectivity is used to investigate the electron and phonon dynamics occurring at the direct band gap of the excitonic insulator Ta 2 NiSe 5 below the critical temperature of its structural phase transition. We find that the phonon dynamics show a strong coupling t... [Phys. Rev. B 97, 115154] Published Mon Mar 26, 2018
