Probing the Nodal Dynamical Electronic States in Bi$_2$Sr$_2$CaCu$_2$O$_8$ by Time- and Angle- Resolved Photoemission

ORAL

Abstract

Ultra-high resolution time- and angle- resolved photoemission (trARPES) 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. The power of trARPES will be discussed in this talk.
