Plan of this talk
1. A synthesis of the phenomenology- a coherent picture to reconcile ARPES, Nernst/
magnetization with quantum oscillations.
2. A microscopic theory accessing key aspects of overall picture.

Interesting description of a candidate strange metal and a descendant pseudogap state with gapless Fermi arcs.
But some difficulties with experiments persist.
