One of the most basic questions in this field is why is the phase diagram so complex that even experiments frequently conflict with each other, let alone conflicts between theories? With the recent quantum oscillation experiments, both in hole-doped and electron-doped cuprates, the overall picture
may be beginning to change and an emergent simplicity may be in sight. I will give my own perspective on Fermi arc, the pseudogap, and the quantum oscillations and argue why the notion of broken symmetry is such a powerful concept in reconciling many apparently conflicting reports.
