On the relative positions of the $2\Delta$ peaks in Raman and tunneling spectra of d-wave superconductors

Andrey V. Chubukov, Nathan Gemelke, Ar. Abanov

We study $B_{1g}$ Raman intensity $R(\Omega )$ and the density of states $N(\omega )$ in isotropic 2D d-wave superconductors. For an ideal gas, $R(\Omega )$ and $N(\omega )$ have sharp peaks at $\Omega =2\Delta$ and…
