Doping Dependence of Many-Body Interactions in Cuprate Superconductors with Laser-Based ARPES

ORAL

Abstract

Laser-based technology has opened the field of angle-resolved photoemission to a variety of new techniques. Compared to synchrotron facilities, laser experiments typically benefit from higher flux, greater resolution and bulk sensitivity, and a system that is more readily modified for specialized experiments. We demonstrate the results of using this system to probe bosonic renormalization and electron-electron effects at varied dopings and temperatures in the double-layered cuprate Bi-2212.
