Single reconstructed Fermi surface pocket in an underdoped single-layer cuprate superconductor
Abstract
The identification of broken symmetry states in underdoped cuprate superconductors via quantum oscillation measurements remains inconclusive. Here, Chan et al. report the reconstructed Fermi surface of HgBa2CuO4+δ comprises only a single pocket indicating a biaxial charge-density-wave order within each CuO2plane.
