✦ Synopsis
High resolution angle resolved photoemission spectroscopy (ARPES) is used to study the temperature and momentum dependence of the quasiparticle dispersion in optimally doped Bi2212 superconductors. Coupling to bosonic excitations, manifested in the form of a kink in the dispersion, are reported at the nodal and antinodal region. Difference and similarities between the nodal and antinodal kink structure are discussed and coupling to phonon modes is presented as possible explanation.
