Pervasive electronic nematicity as the parent state of kagome superconductors
Muxian Xu, Siyu Cheng, Andrea Capa Salinas +10
Kagome superconductors VSb ( = Cs, K, Rb) have developed into an exciting playground for realizing and exploring exotic solid state phenomena. Abundant experimental e…
The parent state in kagome metals and superconductors: Chiral-nematic Fermi liquid state
Zihao Huang, Zhan Wang, Hengxing Tan +8
The kagome metals and superconductors hosting rich correlated and topological electronic states have captivated quantum materials research. These states are triggered by an unconve…
Reconstructing the wavefunction of magnetic topological insulators MnBi2Te4 and MnBi4Te7 using spin-resolved photoemission
Xue Han, Jason Qu, Hengxin Tan +7
Despite their importance for exotic quantum effects, the surface electronic structure of magnetic topological insulators MnBi2Te4 and MnBi4Te7 remains poorly understood. Using high…
Coherent Phonon Pairs and Rotational Symmetry Breaking of Charge Density Wave Order in the Kagome Superconductor CsVSb
Qinwen Deng, Hengxin Tan, Brenden R. Ortiz +4
In this work, we perform ultrafast time-resolved reflectivity measurements to study the symmetry breaking in the charge-density wave (CDW) phase of CsVSb. By extracting the…
