Absence of nematic instability and dominant response in the kagome metal CsVSb
Zhaoyu Liu, Yue Shi, Qianni Jiang +12
Ever since the discovery of the charge density wave (CDW) transition in the kagome metal CsVSb, the nature of its symmetry breaking is under intense debate. While evidence…
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…

Yu Pang, Jinjin Liu, Zeyu Xiang +6
This work reports the thermal conductivity of RbV3Sb5 and CsV3Sb5 with three-dimensional charge density wave phase transitions from 80 K to 400 K measured by pump-probe thermorefle…
Evolution of charge density waves from three-dimensional to quasi-two-dimensional in Kagome superconductors Cs(V)Sb ( = Nb, Ta)
Qian Xiao, Qizhi Li, Jinjin Liu +7
The Kagome material ( = K, Rb, Cs) with geometry frustration hosts non-trivial topological electronic structures, electronic nematicity, charge…
Topological insulator spin transistor
Linh T. Dang, Oliver Breunig, Zhiwei Wang +2
When a charge current is injected into the surface state of a topological insulator (TI), the resulting shift of the spin-momentum-locked Fermi surface leads to the appearance of a…
Violation of Emergent Rotational Symmetry in the Hexagonal Kagome Superconductor CsV3Sb5
Kazumi Fukushima, Keito Obata, Soichiro Yamane +6
Superconductivity is caused by electron pairs that are canonically isotropic, whereas some exotic superconductors are known to exhibit non-trivial anisotropy stemming from unconven…
