    • Ultrafast Polarization Switching in BaTiO<inf>3</inf> Nanomaterials: Combined Density Functional Theory and Coupled Oscillator Study 

      Zhilyaev, Petr; Brekhov, Kirill; Mishina, Elena; Tantardini, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-17)
      The challenge of achieving ultrafast switching of electric polarization in ferroelectric materials remains unsolved as there is no experimental evidence of such switching to date. In this study, we developed an enhanced model that describes switching within a two-dimensional space of generalized coordinates at THz pulses. Our findings indicate that stable switching in barium titanate cannot be ...
