Terahertz pulse-driven collective mode in the nematic superconducting state of Ba1−x K x Fe2As2
Abstract We investigate the collective mode response of the iron-based superconductor Ba1−x K x Fe2As2 using intense terahertz (THz) light. In the superconducting state a THz Kerr signal is observed and assigned to nonlinear THz coupling to superconducting degrees of freedom. The polarization depend...
