Two-Component Dynamics of the Order Parameter of High Temperature Bi₂Sr₂CaCu₂O_8+delta Superconductors Revealed by Time-Resolved Raman Scattering

FIG. 1 . Temporal evolution of the time-resolved Raman difference spectra at an equilibrium temperature of 10 K in B1g geometry.  The contour plot shown in presents 12 Raman difference spectra for different delay times. The dashed line separates two energy regions of the pair-breaking peak that reveal different characteristic behavior. The intensity changes are color coded demonstrating the transfer of spectral weight from high to low energies after 1 ps.
