Structural Phase Separation Couples to Charge-Density-Wave Formation in Kagome Metal FeGe
Boyang Zhao, Youngjun Ahn, Qinwen Deng +7
The intertwining of charge, spin, and lattice degrees of freedom underlies the emergent properties of correlated materials. A recent prominent example is the kagome metal FeGe, whi…
Observation of Room-temperature Charge Density Wave Correlations via Coherent Phonon Spectroscopy in Sn-doped Kagome Superconductor CsVSb
Qinwen Deng, Andrea Capa Salinas, Suchismita Sarker +3
In this work, we perform ultrafast time-resolved reflectivity measurements to track the evolution of charge density wave (CDW) correlations in Sn-doped Kagome superconductor CsV$_3…
Revealing Rotational Symmetry Breaking Charge-density Wave Order in Kagome Superconductor (Rb, K)VSb by Ultrafast Pump-probe Experiments
Qinwen Deng, Hengxin Tan, Brenden R. Ortiz +3
The recently discovered Kagome superconductor AVSb (where A refers to K, Rb, Cs) has stimulated widespread research interest due to its interplay of non-trivial topology an…
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…
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…
Time-resolved magneto-optical effects in the altermagnet candidate MnTe
Isaiah Gray, Qinwen Deng, Qi Tian +4
-MnTe is an antiferromagnetic semiconductor with above room temperature = 310 K, which is promising for spintronic applications. Recently, it was reported to be an alterm…
