“#Electric current is manipulated by light in an organic superconductor” Fig. 1. Spectra of SHG and THG which are emitted by irradiation of 6 fs laser pulses in an organic superconductor, κ-(BEDT-TTF)2Cu[N(CN)2]Br. Observation of the SHG in the centrosymmetric materials indicates a non-linear current which cannot be described by Ohm’s law. Right panel shows the…
