Quantum oscillation experiments have revealed that the Fermi surface of cuprate high-temperature superconductors undergoes a radical transformation as a function of doping. The origin of this Fermi-surface reconstruction and its connection to high-temperature superconductivity are issues at the heart of current debates. Could both be caused by a quantum critical point where some density-wave order sets in?
