abstract
Cluster dynamical mean field methods are used to calculate the superconductivity-induced changes in the interplane conductivity and Raman scattering cross section of the two dimensional Hubbard model. When superconductivity emerges from the pseudogap, the superconducting response is found to be diminished in amplitude, broadened and, in the case of the interplane conductivity, shifted to higher frequency. The results are in agreement with data on high temperature copper-oxide superconductors indicating that the Hubbard model contains the essential low energy physics of the pseudogap and its interplay with superconductivity in the cuprates.

Dynamical Charge Susceptibility in the Hubbard Model
The dynamical charge susceptibility of the 2D Hubbard model in the pseudogap regime shows weak momentum and temperature dependence and no clear pseudogap signature, based on eight-site dynamical cluster approximation calculations.
