dc.descriptionWe study the dynamics of the superconducting order parameter in the high-$T_c$ cuprate Bi$_2$Sr$_2$CaCu$_2$O$_{8-δ}$ by employing a novel time-resolved pump-probe Raman experiment. We find two different coupling mechanisms that contribute equally to the pair breaking peak. One coupling sets in very fast at 2ps and relaxes slow, while the other one is delayed and sets in roughly at 5ps and relaxes fast. A model that couples holes through phonons is able to reproduce one part of the condensate dynamics, thus, we argue that hole-spin interactions are of importance as well.
