Cleavage-History-Dependent Low-Temperature ARPES Spectra of Charge-Ordered EuAl
Hao Liu, Bo Chen, Chen Zhang +9
Charge ordering in EuAl has been widely discussed in connection with band reconstruction, magnetism, and topological electronic states, yet the microscopic origin of the comple…
Termination-Dependent Surface States and Magnetic Fingerprints of Chiral Helimagnet Cr1/3TaS2
Bo Liang, Xue Li, Congcong Le +36
Chiral helimagnets based on intercalated transition-metal dichalcogenides, characterized by nano-scale spin ordering, provide a powerful route to engineer chiral spin textures (e.g…
Observation of hidden altermagnetism in CsVTeO
Guowei Yang, Ruihan Chen, Changchao Liu +25
Altermagnets are characterized by anisotropic band/spin splittings in momentum space, dictated by their spin-space group symmetries. However, the real-space modulations of altermag…
Ultrafast photoinduced phase transition in the antiferromagnetic Dirac semimetal EuAgAs
Hao Liu, Chen Zhang, Qi-Yi Wu +12
We report the observation of a light-induced subpicosecond phase transition in the antiferromagnetic Dirac semimetal EuAgAs, achieved through ultrafast optical excitation. Using ul…
