Fractional phase slips across the charge-density-wave domain walls in 1-T TiSe2
Haotian Zhang, Zihao Song, Zhongchen Xu +9
The microscopic origin of the charge density wave (CDW) in 1\textit{T}-TiSe remains controversial, with competing scenarios based on phonon-driven lattice instability and elect…
Quantum fluctuations associated with first-order magnetic transition in a frustrated kagome lattice antiferromagnet
Zhongchen Xu, Xinyang Liu, Cuiwei Zhang +7
Intense quantum fluctuations arising from geometrical frustrations in kagome-lattice magnets provide a feasible approach to exotic quantum states. Here, we document an unexpected i…
Magnetization plateau and anisotropic magnetoresistance in the frustrated Kondo-lattice compound Ce3ScBi5
Zhongchen Xu, Yaxian Wang, Cuiwei Zhang +6
Kondo metals with geometric frustration offer fertile ground for exploring exotic states of matter with a field-induced fractional magnetization platform and nonsaturating magnetor…
Quasi-linear magnetoresistance and paramagnetic singularity in Hypervalent Bismuthide
Zhongchen Xu, Yi Yan, Zhihao Liu +7
Materials featuring hypervalent bismuth motifs have generated immense interest due to their extraordinary electronic structure and exotic quantum transport. In this study, we synth…
A non-invasive dry-transfer method for fabricating mesoscopic devices on sensitive materials
Zhongmou Jia, Yiwen Ma, Zhongchen Xu +18
Many materials with novel or exotic properties are highly sensitive to environmental factors such as air, solvents, and heat, which complicates device fabrication and limits their…
Highly tunable valley polarization of potential-trapped moiré excitons in WSe2/WS2 heterojunctions
Yueh-Chun Wu, Matthew DeCapua, ZhongChen Xu +4
Moiré superlattices created by stacking atomic layers of transition metal dichalcogenide semiconductors have emerged as a class of fascinating artificial photonic and electronic m…
