Coupling to a phononic mode in $B{i}_{2-x}P{b}_{x}S{r}_{2}CaC{u}_2{O}_{8+\delta }$: Angle-resolved photoemission

B. Ziegler, B. Müller, A. Krapf +3

The kink in the dispersion and the drop in the width observed by angle-resolved photoemission in the nodal direction of the Brillouin zone of $\mathrm{Bi_{2-x}Pb_xSr_2CaCu_2O_{8+ δ…
