Through a Lattice Darkly: Shedding Light on Electron-Phonon Coupling in the High Tc Cuprates

Figure 4

ARPES MDC dispersion data taken optimally doped ( = 92 K) as discussed in [16]. Near antinodal point data (see inset) comparing (a) dispersion and (b-c) FWHM showing that the ARPES kink energy is shifted to lower energy when passing above . The MDC FWHM is related to the Im.
