Abstract

We have performed high-resolution angle-resolved photoemission spectroscopy on high-T c superconductors La 1.85Sr 0.15CuO 4 (LSCO) and Bi 2Sr 2CaCu 2O 8+δ (Bi2212) to study the universality of manybody interaction in hole-doped high-Tc superconductors. We found that the emergence of kink in the dispersion in the off-nodal region at the superconducting state is a common feature, while the energy scale of kink is remarkably different between LSCO and Bi2212. We conclude that the coupling of electrons with spin excitations at the off-nodal region is universal in hole-doped high-T c cuprates.
