Extraction of Absolute Electron Self-Energy from Angle-Resolved Photoemission Measurements on Pb-Bi220

ORAL

Abstract

VUV Laser-based angle-resolved photoemission spectroscopy measurements with super-high resolution have been carried out on heavily over-doped Pb-Bi2201 high temperature superconductors with Tc$<$5K. Along nodal direction, a new approach is developed to determine the real bare band which makes it possible to determine the absolute electron self-energy and abstract the real bare band.
