  • Abstract
    Femtosecond-resolved polarimetry characterizes a two-step polarization recovery after non-equilibrium photoexcitation of BaFe2As2. This underpins the nematicity as an independent degree of freedom responsible for the anisotropy, which demonstrates a benchmark approach to anisotropic quantum fluids.
