Anomalous narrow-band correlation in a natural superconducting heterostructure
Xiupeng Sun, Zhiyuan Wei, Min Shan +11
A new frontier in condensed matter physics is to stack atomically thin layered-materials with different properties and create intriguing phenomena which do not exist in any of the…
Distinct band reconstructions in kagome superconductor CsVSb
Yang Luo, Shuting Peng, Samuel M. L. Teicher +12
The new two-dimensional (2D) kagome superconductor CsVSb has attracted much recent attention due to the coexistence of superconductivity, charge order, topology and kagome…
Tunable van Hove singularity without structural instability in Kagome metal CsTiBi
Bo Liu, Minquan Kuang, Yang Luo +12
In Kagome metal CsVSb, multiple intertwined orders are accompanied by both electronic and structural instabilities. These exotic orders have attracted much recent attention…
Evidence of electron interaction with an unidentified bosonic mode in superconductor CsCaFeAsF
Peng Li, Sen Liao, Zhicheng Wang +16
The kink structure in band dispersion usually refers to a certain electron-boson interaction, which is crucial in understanding the pairing in unconventional superconductors. Here…
A unique van Hove singularity in kagome superconductor CsVTaSb with enhanced superconductivity
Yang Luo, Yulei Han, Jinjin Liu +23
Van Hove singularity (VHS) has been considered as a driving source for unconventional superconductivity. A VHS in two-dimensional (2D) materials consists of a saddle point connecti…
Charge-order-assisted topological surface states and flat bands in the kagome superconductor CsVSb
Yong Hu, Samuel M. L. Teicher, Brenden R. Ortiz +8
The diversity of emergent phenomena in quantum materials often arises from the interplay between different physical energy scales or broken symmetries. Cooperative interactions amo…
Flat bands and distinct density wave orders in correlated Kagome superconductor CsCrSb
Shuting Peng, Yulei Han, Yongkai Li +15
Kagome metal CsVSb has attracted much recent attention due to the coexistence of multiple exotic orders and the associated proposals to mimic unconventional high temperatur…
Two-dimensional phase diagram of the charge density wave in doped CsVSb
Linwei Huai, Hongyu Li, Yulei Han +15
Kagome superconductors AVSb (A = K, Rb and Cs) have attracted much recent attention due to the coexistence of multiple exotic orders. Among them, the charge density wave (C…
Electronic-correlation-assisted charge stripe order in a Kagome superconductor
Linwei Huai, Zhuying Wang, Huachen Rao +12
A central mystery in high-temperature cuprate superconductors is the coexistence of multiple exotic orders, which is presumably associated with strong electronic correlation. The o…
