Abstract
Although the low-frequency electronic Raman response in the superconducting state of the cuprates can be largely understood in terms of a d-wave energy gap, a long-standing problem has been an explanation for the spectra observed in the A1g polarization orientations. We present calculations which suggest that the peak position of the observed A1g spectra is due to a collective spin fluctuation mode.
