Quantum oscillations reveal electron pocket in underdoped cuprates

Researchers propose a model where pseudogap 'Fermi arcs' in cuprates reconstruct into a single electron pocket with charge density wave order in high magnetic fields. Computations show this matches quantum oscillations seen in experiments.
