The spin resonance and high frequency optical properties of the cuprates

Abstract

We argue that recently observed superconductivity-induced blue shift of the plasma frequency $\delta {\omega }_{pl}$ in $B{i}_{2}S{r}_{2}CaC{u}_2{O}_{8+\delta }$ is related to the change in the integrated dynamical structure factor associated with the development of the spin resonance below $T_c$. We show that the magnitude of $\delta {\omega }_{pl}$ is consistent with the small integrated spectral weight of the resonance, and its temperature dependences closely follow that of the spin resonance peak.
