Fermi Surface and Pseudogap Evolution in a Cuprate Superconductor
Fermi Surface and Pseudogap Evolution in a Cuprate Superconductor
Under the Dome The superconducting transition temperature T c of copper oxides has a dome-shaped dependence on chemical doping. Whether there is a quantum critical point (QCP) beneath the dome, and whether it is related to the enigmatic pseudogap, has been heavily debated. Two papers address this question in two …
