Description
The role of antiferromagnetism in high Tc cuprates remains at the center of understanding the superconductivity in these systems. During this talk I will present some of our recent results on electron doped high Tc cuprates and show the dual role that antiferromagnetic fluctuations seem to play in the electron doped cuprates*. An intriguing link between electron-phonon coupling and the strength of antiferromagnetic fluctuations will also be elucidated. As an outlook, the ongoing work on directly detecting and characterizing Cooper pairs using 2e-ARPES will also be briefly described.
