Emergence of the electronic states driven by quantum charge fluctuations in electron doped cuprate superconductors
The study used ARPES and IPES to investigate electron-doped cuprates, looking for electronic states driven by quantum charge fluctuations. Researchers found emergent spectral features in both occupied and unoccupied states consistent with these fluctuations. This provides direct experimental evidence that charge dynamics significantly shape the electronic structure of these superconductors.
