Stripe order, electron pockets, and Fermi arcs

The recent observation of an electron pocket by quantum oscillation experiments is naturally explained by the presence of magnetic stripe order near 1/8 hole doping in cuprates [1]. A bigger question is how these observations are related to other phenomena in the phase diagram - the pseudogap phase, quantum critical points, and Fermi arcs [2], and the implications this might have for the origin of high temperature superconductivity.\\[4pt] [1] A.
