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…
Fluctuated lattice-driven charge density wave far above the condensation temperature in kagome superconductor KVSb
Haoran Liu, Shaofeng Duan, Xiangqi Liu +9
The kagome material AVSb exhibits multiple exotic orders, including an unconventional charge density wave (CDW). Elucidating the underlying mechanism behind the CDW transit…
Identification of metastable lattice distortion free charge density wave at photoinduced interface via TRARPES
Shaofeng Duan, Binshuo Zhang, Zihao Wang +8
The interplay between different degrees of freedom governs the emergence of correlated electronic states in quantum materials, with charge density waves (CDW) often coexisting with…
