dc.description.abstractUltrafast broadband transient reflectivity experiments are performed to study the interplay between the nonequilibrium dynamics of the pseudogap and the superconducting phases in Bi2Sr2Ca0.92Y0.08Cu2O8+δ. Once superconductivity is established, the relaxation of the pseudogap proceeds ∼2 times faster than in the normal state, and the corresponding transient reflectivity variation changes sign after ∼0.5  ps. The results can be described by a set of coupled differential equations for the pseudogap and for the superconducting order parameter. The sign and strength of the coupling term suggest a remarkably weak competition between the two phases, allowing their coexistence.eng
