Decoupled interband pairing in a bilayer iron-based superconductor evidenced by ultrahigh-resolution ARPES
Shichong Wang, Yuanyuan Yang, Yang Li +11
We present direct experimental evidence of a weakly coupled multiband superconducting state in the bilayer iron-based superconductor ACaFeAsF (A = K, Cs) via ultrah…
Resolving Phonons in Superconductor Bi2Sr2CaCu2O8+δ at Sub-Unit-Cell Resolution
Xiaowen Zhang, Jiade Li, Xiaoyue Gao +9
The role of phonons in cuprates remains controversial, with their complex lattice structure complicating the investigation. Here, we identify phonon modes originating from charge r…
A sample-position-autocorrection system with precision better than 1 \um~in angle-resolved photoemission experiments
Shaofeng Duan, Shichong Wang, Yuanyuan Yang +4
We present the development of a high-precision sample-position-autocorrection system for photoemission experiments. A binocular vision method based on image pattern matching calcul…
Anomalous contribution to the nematic electronic states from the structural transition in FeSe revealed by time- and angle-resolved photoemission spectroscopy
Yuanyuan Yang, Qisi Wang, Shaofeng Duan +8
High-resolution time- and angle-resolved photoemission measurements were made on FeSe superconductors. With ultrafast photoexcitation, two critical excitation fluences that corresp…
Unusual band splitting and superconducting gap evolution with sulfur substitution in FeSe
Yuanyuan Yang, Qisi Wang, Shaofeng Duan +7
High-resolution angle-resolved photoemission measurements were taken on FeSeS (x=0, 0.04, and 0.08) superconductors. With an ultrahigh energy resolution of 0.4 meV, unu…
