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…
Lyman- polarization from cosmological ionization fronts: II. Implications for intensity mapping
Emily Koivu, Heyang Long, Yuanyuan Yang +1
This is the second paper in a series whose aim is to predict the power spectrum of intensity and polarized intensity from cosmic reionization fronts. After building the analytic mo…
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…
Optical manipulation of electronic dimensionality in a quantum material
Shaofeng Duan, Yun Cheng, Wei Xia +9
Exotic phenomenon can be achieved in quantum materials by confining electronic states into two dimensions. For example, relativistic fermions are realised in a single layer of carb…
A time- and angle-resolved photoemission spectroscopy with probe photon energy up to 6.7 eV
Yuanyuan Yang, Tianwei Tang, Shaofeng Duan +3
We present the development of a time- and angle-resolved photoemission spectroscopy based on a Yb-based femtosecond laser and a hemispherical electron analyzer. The energy of the p…
Non-Coulomb strong electron-hole binding in revealed by time- and angle-resolved photoemission spectroscopy
Tangwei Tang, Hongyuan Wang, Shafeng Duan +5
We reveal an ultrafast purely electronic phase transition in \TNS, which is a plausible excitonic insulator, after excited by an ultrafast infrared laser pulse. Specifically, the o…
