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

Figure 3

ARPES MDC dispersion data taken optimally doped ( = 92 K) as discussed in [16]. Nodal point data (see inset) comparing (a) dispersion and (b-c) MDC full width half max (FWHM) showing little change in the energy of the ARPES kink with . The MDC FWHM is related to the Im.
