Real-Time Observation of Cuprates Structural Dynamics by Ultrafast Electron Crystallography
Figure 12
BSCCO and LCO optical spectra and temperature dependence. (a) The difference spectrum for Bi2223 is displayed; the low-energy region is magnified in the inset. (b) The optical conductivity of Bi2223 at different temperatures is shown together with a Drude-Lorentz decomposition of the spectrum; the low-energy region is magnified in the inset. (c) The optical conductivity of different cuprates is shown for comparison, together with the theoretical spectrum obtained in LCO by the charge-stripes model.
