中文摘要 | Super-high-resolution laser-based angle-resolved photoemission measurements have been performed on a high-temperature superconductor, Bi2Sr2CaCu2O8. The band back-bending characteristic of the Bogoliubov-like quasiparticle dispersion is clearly revealed at low temperature in the superconducting state, which gives rise to two peaks in the momentum distribution curves. This makes it possible to experimentally extract the normal electron self-energy and pairing self-energy in the superconducting state. The resultant normal and pairing self-energies exhibit features at similar to 54 and similar to 40 meV, in addition to the superconducting gap-induced structure at lower binding energy and a broad featureless structure at higher binding energy. This information can be used to further determine the Bosonic spectral function that will provide key insight and constraints on the origin of electron pairing in high-temperature superconductors. |
