Ultra-High Resolution Time- and Angle-Resolved Photoemission Experiments on High Temperature Superconductor Bi$_2$Sr$_2$CaCu$_2$O$_8$

ORAL

Abstract

Ultra-high resolution laser-based time- and angle-resolved photoemission measurements have been carried out on various dopings of Bi$_2$Sr$_2$CaCu$_2$O$_8$ high temperature superconductor. In this talk, we will report on the study of the dynamical quasiparticle excitation and recombination of the nodal electronic states in cuprate.
