Local atomic configuration control of superconductivity in the undoped pnictide parent compound BaFe2As2
Jong-Hoon Kang, Philip J. Ryan, Jong-Woo Kim +13
Emergent superconductivity is strongly correlated with the symmetry of local atomic configuration in the parent compounds of iron-based superconductors. While chemical doping or hy…

Discovery of Terahertz Second Harmonic Generation from Lightwave Acceleration of Symmetry--Breaking Nonlinear Supercurrents
C. Vaswani, C. Sundahl, M. Mootz +11
We report terahertz (THz) second harmonic generation (SHG) in superconductors (SC) with inversion symmetric equilibrium states that forbid even-order nonlinearities. Such SHG signa…
