Observation of Giant Nernst plateau in ideal 1D Weyl Phase
Yong Zhang, Qi Li, Penglu Zhao +7
The search for a giant Nernst effect beyond conventional mechanisms offers advantages for developing advanced thermoelectric devices and understanding charge-entropy conversion. He…
Observation of quantum oscillations near the Mott-Ioffe-Regel limit in CaAs3
Yuxiang Wang, Minhao Zhao, Jinglei Zhang +24
The Mott-Ioffe-Regel limit sets the lower bound of carrier mean free path for coherent quasiparticle transport. Metallicity beyond this limit is of great interest because it is oft…
Evidence for Unfolded Fermi Surfaces in the Charge-Density-Wave State of Kagome Metal FeGe Revealed by de Haas-van Alphen Effect
Kaixin Tang, Hanjing Zhou, Houpu Li +10
The antiferromagnetic kagome lattice compound FeGe has been revealed to host an emergent charge-density-wave (CDW) state which manifests complex interplay between the spin, charge…
Extreme orbital ab-plane upper critical fields far beyond Pauli limit in 4Hb-Ta(S, Se)2 bulk crystals
Fanyu Meng, Yang Fu, Senyang Pan +6
Transition metal disulfides 4Hb-Ta(S, Se)2 with natural heterostructure of 1T- and 1H-Ta(S, Se)2 layers have became the focus of correlated materials their unique combinations of M…
Absence of metallicity and bias-dependent resistivity in low-carrier-density EuCd2As2
Yuxiang Wang, Jianwen Ma, Jian Yuan +10
EuCd2As2 was theoretically predicted to be a minimal model of Weyl semimetals with a single pair of Weyl points in the ferromagnet state. However, the heavily p-doped EuCd2As2 crys…
The Ground State Lattice Distortion of CsVSb Revealed by de Haas-van Alphen Oscillations
Senyang Pan, Feng Du, Yong Zhang +10
The recently discovered AVSb (A = K, Rb, Cs) compounds have garnered intense attention in the scientific community due to their unique characteristics as kagome superco…
