Unconventional exciton evolution from the pseudogap to superconducting phases in cuprates

HIGHLIGHTS

  • who: A. Singh from the (UNIVERSITY) have published the research: Unconventional exciton evolution from the pseudogap to superconducting phases in cuprates, in the Journal: (JOURNAL) of 18/Nov/2022
  • what: The authors show that excitonic excitation of optimally doped Bi2Sr2CaCu2O8+u03b4 with energy far above the superconducting-gap energy scale, about 1 eV or even higher, is unusually enhanced by the onset of superconductivity. The authors used RIXS to study electron-hole-pair (i.e., excitonic) excitation in cuprates and identified new phenomena that are critical to understanding the pseudogap and the superconductivity.
