    • Imaging an isolated water molecule using a single electron wave packet 

      Liu, Xinyao; Amini, Kasra; Steinle, Tobias; Sánchez, Aurelien; Belsa Carné, Blanca Maria; Moniruzzaman, Shaikh; Steinmetzer, Johannes; Anh-Thu, Le (American Institute of Physics (AIP), 2019-07-14)
      Article
      Accés obert
      Observing changes in molecular structure requires atomic-scale Ångstrom and femtosecond spatio-temporal resolution. We use the Fourier transform (FT) variant of laser-induced electron diffraction (LIED), FT-LIED, to directly ...

    • Imaging an isolated water molecule with an attosecond electron wave packet 

      Liu, Xinyao; Amini, Kasra; Steinle, Tobias; Sánchez, Aurelien; Moniruzzaman, Shaikh; Belsa Carné, Blanca Maria; Steinmetzer, Johannes; Anh-Thu, Le; Moshammer, Robert; Pfeifer, Thomas; Ullrich, Joachim; Moszynski, Robert; Lin, Chii-Dong; Gräfe, Stefanie; Biegert, Jens (Institute of Physics (IOP), 2020-01-01)
      Article
      Accés obert
      We use laser-induced electron diffraction (LIED) to self-image the molecular structure of an isolated water molecular ion using its own retuning attosecond electron wave packet (EWP). Using LIED’s sub-femtosecond and ...

    • Laser-induced electron diffraction of the ultrafast umbrella motion in ammonia 

      Belsa Carné, Blanca Maria; Amini, Kasra; Liu, Xinyao; Sánchez, Aurelien; Steinle, Tobias; Steinmetzer, Johannes; Biegert, Jens (AMER INST PHYSICS, 2021-01-13)
      Article
      Accés obert
      Visualizing molecular transformations in real-time requires a structural retrieval method with Ångström spatial and femtosecond temporal atomic resolution. Imaging of hydrogen-containing molecules additionally requires an ...

    • Laser-induced electron interferences from atoms and molecules 

      Sánchez, Aurelien (Universitat Politècnica de Catalunya, 2022-07-25)
      Tesi
      Accés obert
      Since discovering wave-particle duality, science has changed our perception of light and matter, especially at the subatomic level. Thanks to such discoveries, we have been able to develop and expand our scientific knowledge ...

    • Molecular structure retrieval directly from laboratory-frame photoelectron spectra in laser-induced electron diffraction 

      Sánchez, Aurelien; Amini, Kasra; Belsa Carné, Blanca Maria; Liu, Xinyao; Steinle, Tobias; Biegert, Jens (2021-03-09)
      Article
      Accés obert
      Ubiquitous to most molecular scattering methods is the challenge to retrieve bond distance and angle from the scattering signals since this requires convergence of pattern matching algorithms or fitting methods. This ...

    • Ultrafast imaging of the Renner-Teller effect in a field-dressed molecule 

      Amini, Kasra; Sclafani, Michele; Steinle, Tobias; Moniruzzaman, Shaikh; Sánchez, Aurelien; Liu, Xinyao; Anh-Thu, Le; Steinmetzer, Johannes; Pfeiffer, Thomas; Moshammer, Robert; Ullrich, Joachim; Lewenstein, Maciej; Moszynski, Robert; García de Abajo, Francisco Javier; Lin, Chii-Dong; Gräfe, Stefanie; Biegert, Jens (Institute of Physics (IOP), 2020-01-01)
      Article
      Accés obert
      We present experimental results of linear-to-bent transition of field-dressed molecules, mediated by Renner-Teller effect. Using the state-of-the-art laser-induced electron diffraction (LIED) technique, we image a bent and ...
