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…
Spin-orbit-enabled Fermi-surface splitting in noncollinear antiferromagnetic SmBi
Long Zhang, Ming Cheng, Jingyu Li +10
Spin-split electronic structures in compensated antiferromagnets are commonly sought in the nonrelativistic limit, where magnetic order lifts spin degeneracy without spin-orbit cou…
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…
Evidence of P-wave Pairing in KCrAs Superconductors from Phase-sensitive Measurement
Zhiyuan Zhang, Ziwei Dou, Anqi Wang +21
P-wave superconductors hold immense promise for both fundamental physics and practical applications due to their unusual pairing symmetry and potential topological superconductivit…
Incommensurate Charge Super-modulation and Hidden Dipole Order in Layered Kitaev Material -RuCl
Xiaohu Zheng, Zhengxin Liu, Cuiwei Zhang +5
The magnetism of Kitaev materials has been widely studied, but their charge properties and the coupling to other degrees of freedom are less known. Here we investigate the charge s…
Multiple charge-density-wave gaps in LaSbTe and CeSbTe as revealed by ultrafast spectroscopy
Liye Cao, Cuiwei Zhang, Yi Yang +5
Utilizing ultrafast time-resolved pump-probe spectroscopy measurements, we investigate the photoinduced quasiparticle dynamics of the topological materials LaSbTe and CeSbTe. In La…
