Evidence for two-component high-temperature superconductivity in the femtosecond optical response of YBa2Cu3O7-delta
Femtosecond time-resolved spectrocopy has been used to investigate electronic excitations contributing to the superconducting gap function Δ(ω, T) in YBa 2Cu 3O 7-δ. The optical response is strongly peaked at 1.5 eV, and contains two distinct components: one with a characteristic relaxation time of...
