dc.descriptionUsing a widefield pump-probe microscope (with ~10 nm spatial precision and ~10 fs time resolution) we probe the temperature and fluence dependent dynamics of the collective modes in excitonic insulator candidate Ta2NiSe5. We pump with a broadband pulse centered around 500 nm and probe ~800 nm using a bandpass filter.
dc.description.sponsorshipThe calculations were run on the Beo05 cluster at the University of Fribourg. We acknowledge the CECAM workshop “Excitonic insulator: New perspectives in long-range interacting systems” at EPFL Lausanne for insights and discussions and for providing the opportunity to start this collaboration. We also thank A. Boris (Max Planck Institute for Solid State Research) and A. Musser (Cornell University) for helpful discussions.
