Amplitude mode in a multi-gap superconductor MgB investigated by terahertz two-dimensional coherent spectroscopy
Kota Katsumi, Jiahao Liang, Ralph Romero +3
We have investigated the terahertz (THz) nonlinear response of the multigap superconductor MgB, using THz two-dimensional coherent spectroscopy (THz 2DCS). With broadband THz d…
