Abstract

We argue that recently observed superconductivity-induced blue shift of the plasma frequency \ensuremathδ\ensuremathω_pl in Bi₂Sr₂CaCu₂O_8+\ensuremathδ [Molegraaf et al., Science 295, 2239 (2002)] 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 \ensuremathδ\ensuremathω_pl is consistent with the small integrated spectral weight of the resonance, and its temperature dependences closely follow that of the spin-resonance peak. We also discuss the differential optical integral for the conductivity.
