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…
Structural contribution to light-induced gap suppression in TaNiSe
Zijing Chen, Chenhang Xu, Chendi Xie +13
An excitonic insulator is a material that hosts an exotic ground state, where an energy gap opens due to spontaneous condensation of bound electron-hole pairs. TaNiSe is a…
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…
